Police release sketch of bridge mugger

Police officials released a sketch today of man who mugged and pistol-whipped an off-duty Philadelphia police detective on the Ben Franklin Bridge on Tuesday.

The female detective was jogging across the bridge at about 7 a.m. when the suspect, who was riding a 10-speed bike, approached. The robber cracked the detective in the face with a handgun and stole her 16-inch gold rope chain. The attacker is described as a stocky, 5-feet-6 white or Hispanic man, age 25 to 30, with an olive complexion and unkempt hair, police said.
