Unfortunately, he did have an issue outside of Sesame Street in the early eighties. There are a lot of misconceptions and rumors about these events. Here are two articles from around 1980 that describe the incident.
Even though these events are quite discouraging and very heartbreaking, try not to let them dilute your enjoyment of Northern's talented and versatile performances on Sesame Street. I have been told by numerous people how much he loved working on Sesame Street and that people loved him as well.

Sesame Street Actor Charged In Neighborhood Rampage Here
by Randy Hilman
An actor on the popular children's television series Sesame Street was charged here yesterday with staging a rampage on Graybar Lane after apparently going berserk, police said.
Northern J. Calloway, 32, of New York City, was subdued by three police officers after having beaten a woman with an iron rod, smashing the windows of one house, breaking into and vandalizing a second residence and breaking the windshield of an automobile, officers said.
"I'm David of Sesame Street and they're trying to kill me," screamed Calloway after metro ambulance personnel strapped the man--dressed only in a tee-shirt--onto a stretcher near the intersection of Graybar Lane and Benham Avenue.
"I still don't know what went wrong with him." said Sgt. Joel Goodwin. "When the officers finally captured him, he was saying all kinds of strange things, and he appeared to be trying to eat the grass."
The sergeant said Calloway was taken first to Vanderbilt Hospital for emergency treatment of cuts he suffered while breaking out the windows of two homes.
Later, he was transported to Middle Tennessee Health Institute for observation. The children's actor has been charged with aggravated assault in connection with the beating of Mary Stagaman, 27, a resident of Villager Condominiums, 3600 Hillsboro Road. She was listed in stable condition in Vanderbilt Hospital's intensive care unit with head injuries and broken ribs.
Miss Stagaman, director of marketing for the Tennessee Performing Arts Center, had received Calloway as her house guest following his performance Saturday in "David of Sesame Street" at the center. Calloway plays the role regularly on the popular children's program on educational television.
TPAC officials expressed surprise that the actor still was in Nashville, noting that Calloway, who mentioned that he was exhausted from his hectic performing schedule, claimed he had to return to New York last Sunday for Monday morning taping sessions of Sesame Street.
"The whole thing is a mystery to me," said Warren Sumners, TPAC managing director. "It's not uncommon for a performer like this to be tired and be on tight schedules. But he was marvelous to work with.
"He must have come back to Nashville sometime this week," Sumners added.
Goodwin said police received a call about 9 a.m. yesterday that a naked person was running through the neighborhood, screaming and wreaking havoc. When officers Raymond McWhorter and James Murphy arrived on Graybar Lane, they saw a "wild man wearing only a T-shirt" running down the street, the sergeant added.
"The two officers chased him on foot and caught up with him at one point, but he was real sweaty and slipped free. Officer (Steve) Anderson joined in the chase and the three of them caught Calloway at Glen Echo Road and Benham Avenue and put the cuffs on him. He was wild."
Goodwin, tracing the path of the man during the 45-minute incident, said Calloway apparently left Miss Stagaman's condominium shortly before 9 a.m. and began running back and forth the 1900 block of Graybar Lane, moving in an easterly direction.
"From what we can tell, he smashed out a large plate-glass window and storm door at 2000 Graybar Lane, but didn't enter the residence there," Goodwin said.
Cut from the broken glass, Calloway then ran to a residence at 1932 Graybar Lane, broke into the home, and demolished the interior of that residence.
The owners of the homes could not be reached for comment.
Goodwin said Calloway then ran out into the street and took a schoolbook bag from a youngster waiting for the school bus. After taking the bag, he picked up a large rock and smashed out the windshield of a parked Volkswagen, the officer added.
"He tried to get into a number of cars and left a trail of blood wherever he ran," Goodwin said. One man, Douglas Wright, of 1770 Hillmont Drive, said he fired a shot at the man.
"My wife and I saw the man run, naked, into our garage," said Wright.

An actor on the television series "Sesame Street" says he doesn't know what caused him to go on an alleged rampage in which police say he ran nearly naked through a neighborhood, breaking windows.
"It will be a sad, sad thing for the children to hear about this," said Northern J. Calloway, who plays the affable David on the award-winning Public Broadcasting Service children's series.
"I can't remember a thing. I've never had a spell like this before," Calloway, 32, said. General Sessions Judge Gale Robinson ordered Calloway held without bond on aggravated assault charges and approved his transfer to the Middle Tennessee Mental Health Institute.
During the alleged rampage Friday morning, a Nashville woman with whom Calloway reportedly was staying was seriously injured after being beaten with an iron.
Screaming "I'm David of 'Sesame Street' and they're trying to kill me," Calloway, wearing only a T-shirt, was strapped by ambulance workers onto a stretcher at a city intersection and covered with a sheet. The New York actor was taken to Vanderbilt Hospital for treatment of cuts police said he received while breaking out windows in two homes.
Calloway was in Nashville last weekend to perform at the opening of the Tennessee Performing Arts Center, and officials said they thought he had left town last Sunday.
Police said Mary Stagaman, 27, marketing director for the arts center, was beaten on the head and chest with an iron. She was in serious condition Saturday in Vanderbilt Hospital's intensive care unit, suffering from broken ribs and head injuries.
