City homicide detectives have arrested a man accused of slashing a cyclist's throat in the South Side last month.

Anthony Scholl, 21, of West Mifflin, is accused of following cyclist Colin Albright as he was carrying his bike up the city steps in the South Side and stabbing him in the arms, neck and head before slashing his throat, around 11 p.m. on Sept. 5. At the time, police said that Albright thought he might have cut off his assailant's vehicle at an intersection in the South Side.

Scholl is currently incarcerated at Allegheny County Jail for allegedly lighting his parent's house on fire in West Homestead, according to police. He was taken from the county jail and questioned about the incident at police headquarters where he was arrested this afternoon, police reported in a press release, and his vehicle is being processed for evidence.

Updated 3:40 p.m. Police spokeswoman Diane Richard says via email that West Homestead Police provided information "based on the video we released when this incident occurred. As a result of the video and vehicle description we were lead, through investigative effort, to Mr. Scholl who was in the [Allegheny County Jail] for prior charges in an attempted Arson case."
