A youth who fell asleep in a Muni shelter has a rude Christmas Day awakening, when he found himself in an alley with wounds to the head.

According to the San Francsico Police Department, the 19-year-old victim says he fell asleep at an unknown Muni stop at an unknown time on Sunday, December 25.

What he does know that he woke up somewhere else: The 100 block of Jessie Street, somewhere between Second and Third Streets in SoMa.

When he awoke, he realized that he was suffering from head lacerations, police say. The victim was transported to San Francisco General Hospital for treatment of his injuries. However, since he was "unable to provide/remember any further details," of the incident, police say they have no suspect information to provide in the case.
