Homicide detectives are investigating what led to a 2-month-old boy being hospitalized in extremely critical condition.
Witnesses tell NBC10.com that the child's father came out of his home along the 6200 block of Old York Road in the Ogontz section around 4 p.m. on Friday and screamed for help.
The man was yelling for someone to drive him to the hospital as the child laid limp in his arms. Blood could also be seen coming from the boy's ear, said one witness, who asked not to be named.
That witness then rushed the man and baby to nearby Albert Einstein Medical Center in their own car. Police say the boy was then transferred to St. Christopher's for Children where he remains in extremely critical condition.
Detectives found the injuries to be suspicious and decided to bring the father in for questioning at Philadelphia Police Headquarters.
Police say the mother was at work at the time of the incident.
Back at the home, crime scene investigators removed a bassinet as evidence. Family members tell NBC10.com that they believe the injuries were sustained when that bassinet toppled over.
Still, the investigation continues.
