Providence police are following "substantial leads'' in a weekend assault that left a Brown University basketball player in the hospital with severe head injuries.
Deputy Chief Thomas Oates says police are continuing their investigation into the attack early Sunday morning on 21-year-old Joseph Sharkey of Norwood, Mass.
No arrests have been made.
A spokesman for Rhode Island Hospital said Wednesday that Sharkey remains in critical condition.
Police say a man came up to Sharkey and hit him in the head while he was talking to a group of women around Thayer and George streets on the East Side. Authorities say some kind of altercation took place shortly before the attack.
Sharkey is a sophomore guard. He played high school basketball at Northfield Mount Hermon.
