A Newark police officer saved a man’s life after he was found unresponsive.

Officials say that Officer Claudia Martinez performed CPR on the man early Saturday morning after responding to a medical emergency call on the 500 block of Market Street.

Officials say that the 29-year-old victim was found lying down on the living room floor. Martinez, who was previously a nurse, saw that the man has no pulse and was not breathing. She began performing CPR while her partner called for EMA.

The man’s pulse returned and he began breathing on his own.

“I commend Officer Martinez for applying her training as a licensed practical nurse to perform life-saving chest compressions, reviving an unresponsive man and preventing a tragedy,” Newark Police Director Brian O’Hara said in a statement.

The victim was taken to University Hospital for further treatment.
