A newspaper vendor was arrested one day after police say he stabbed a commuter at a Metro station during the morning rush.
Daniel Richard Brown, 50, turned himself in at a Prince George's County police station Friday morning, police said. He was then turned over to Metro Transit Police.
Brown is facing attempted murder, first-degree assault and other charges.
Police say Brown -- a contractor with Express' parent company, The Washington Post -- argued with a man about 9 a.m. Thursday at the Addison Road-Seat Pleasant station in Capitol Heights, Maryland, Metro spokesman Dan Stessel said.
The attacker surrounded by witnesses and caught on multiple high-definition surveillance cameras then ran away, Stessel said.
"They get into an altercation that escalates to physical, and on the sidewalk ... here, the suspect tackled the victim and ending up stabbing him," he said.
The victim, a 24-year-old man, was taken to a hospital with serious injuries. He was in stable condition Thursday evening.

The Washington Post said the company is looking into what happened.
Commuter Justin Gavin said the suspect handed him a newspaper less than an hour before the attack. "He seemed fine to me," he said.
