A man delivering newspapers early Thursday got an Otay Mesa woman out of her mobile home after he noticed it was on fire, authorities said.

The noninjury fire at the Ocean Bluff Mobile Home Park at 3340 Del Sol Blvd. was reported at 4:57 a.m. and knocked down about 20 minutes later, according to a San Diego fire-rescue dispatcher.

The man called 911 to report the fire but spoke only Spanish and was unable to give an exact address, she said. He then went to the front door of the home and knocked until the woman who lives there heard him and was able to get out.

The woman then got on the phone and was able to provide her address so crews could get there to put out the fire, the dispatcher said.

Arson investigators were called to the scene to help determine what caused the blaze.

The Red Cross was called to assist the woman who lived in the mobile home.

At the scene of the fire, media partner 10News cameras captured police officers putting a man in handcuffs.

Neighbors identified the man as someone who had lived in the mobile home, but was kicked out. 10News learned that the man walked up to the woman with papers in hand. Authorities told 10News the man was arrested on suspicion of violating a restraining order obtained by the woman
