Lancaster police are asking for help to identify three people wanted for an assault that left a 25-year-old Columbia man in critical condition at a hospital.
Investigators on Friday released surveillance video from the Penn Square parking garage where the incident occurred early Sunday.
Police are also seeking three unknown witnesses to the assault.
The victim was unconscious and bleeding from a head injury when officers were called to the parking garage at 20 East King Street around 1:30 a.m.
Witnesses said there had been some type of fight or altercation in the garage and the victim was possibly pushed or fell from about 25 feet to the ground below.
No charges have been filed.
