A College Park man was arrested after he allegedly stabbed a homeless man during an altercation Monday night along Old National Highway in south Fulton County, police said.

The incident happened around 11 p.m. Monday in the 5300 block of Old National Highway.

Fulton County police spokeswoman Kay Lester said that the suspect, 40-year-old Stephen Ellis Cox, had allegedly robbed a woman in the area on Sunday, and “the homeless population had told the offender to leave the area and not come back.”

When Cox returned on Monday night, he was again told by the homeless in the area to leave the area. An altercation broke out and Demarcus Brown, 26, was stabbed in the left side.

According to the police incident report, a responding officer was flagged down by a witness who told the officer that the perpetrator ran into a nearby restaurant and was still inside.

The witness gave the officer a description of the suspect, and when the officer went inside the restaurant, he spotted a man matching that description.

The officer saw the suspect, later identified as Cox, throw a knife under a table and sit down, according to the incident report. The officer drew his weapon, forced Cox to the ground and took him into custody.

Brown was taken to Grady Memorial Hospital for treatment. His condition was not available Tuesday.

Cox was charged with aggravated assault and possession of a knife during the commission of a felony.
