Police say an ice cream truck driver in Maryland was gunned down as he was selling treats to children and a suspect has been arrested.

Frederick police say 22-year-old Brandon Brown was fatally shot Saturday afternoon at Lucas Village, a subsidized housing complex.

Lt. Clark Pennington, a police spokesman, says Brown drove into the community playing music to announce his arrival. He says children were lined up to buy ice cream when Brown stepped out of the truck and was approached by a man who shot him in the chest. Brown died at the scene.

Pennington says witnesses helped police identify a suspect, who was arrested Sunday. Police identified the suspect as 27-year-old Larnell Lyles. His phone number was unlisted, and online court records didn't list an attorney for him.
