(CNN) Police in Maryland have arrested a man wanted on murder charges in a fatal stabbing outside a Popeyes restaurant last week, the Prince George's County Police Department announced early Thursday.

The suspect has been identified as 30-year-old Ricoh McClain, police said in a news release.

The altercation started when 28-year-old Kevin Tyrell Davis cut in line November 4 at the Popeyes in Oxon Hill, Chief Hank Stawinski said at a news conference Thursday. In 15 seconds, it had turned deadly.

Surveillance footage showed several people were waiting in a line set aside for ordering Popeyes' popular new chicken sandwich when Davis entered the store and cut in front of several customers.

McClain confronted Davis about his conduct and moments later the two went outside the restaurant, where McClain stabbed Davis, police said.
