A police officer was injured this morning when he and a wanted man struggled and tumbled out of a second-floor window in Northeast Philadelphia, authorities said.

Officer Ernie Walker, 37, of the 15th District, was treated at Hahnemann University Hospital, for back, neck and head pain and then released, police said. But he was later called back to the hospital for more treatment.

FOP President John McNesby said Walker was admitted to the intensive care unit with cranial bleeding.

"We're making sure the family has everything they need," he said.

The wanted man, whose name has not been released yet, will be charged for assaulting a law enforcement officer and was taken to Aria Health's Frankford hospital with a possible broken leg.

Police said officers went to a house on the 6300 block of Leonard Street in Mayfair about 4:40 a.m. to arrest a man wanted for violating a restraining order.

When the officer tried to take the man into custody in second floor bedroom, he resisted and the two men fell out of a window onto a patio, police said.
