A Philadelphia man is behind bars after an infant was revived with Narcan on Wednesday night after being punctured by a hypodermic needle with drug residue in it.

Philly.com reports that around 6:30 p.m on Wednesday, medics and authorities arrived to a Philadelphia home off of Green Lane, where they found a 9-month-old infant girl unresponsive. According to police, that baby was poked on her leg by a drug-filled needle while she slept in the bed in with her father, 35-year-old Steven Welsh. Apparently, the baby rolled over in her sleep onto the needle.

It’s clear unclear if heroin or a mix of heroin and additional drugs was in the needle. Investigators are still trying to determine what the residue on the end of the needle was. Medical professionals revived the baby with Narcan, a drug often given to reverse the effects of an opioid overdose. The baby survived and is undergoing medical observation.

Welsh was arrested and charged with aggravated assault, endangering the welfare of a child, simple assault and reckless endangerment.

The Special Victims Unit is currently investigating the case. Check back with Crime Online as additional details become available.
