SAN DIEGO -- A suspected burglar was arrested Monday after he kicked down an apartment door in Oak Park, prompting a woman inside to shoot the intruder, police said.

The suspect was arrested after he turned up overnight at Paradise Valley Hospital with a graze wound, San Diego police Sgt. David Jennings said.

He and another suspect, who got away empty handed, banged on the woman's door in the 6400 block of College Grove Drive around 10:20 p.m. Sunday, the sergeant said.

The woman said the men were yelling at her to let them in as she stood on a balcony. When she refused, they began kicking the door, prompting her to get a shotgun, according to Jennings.

She fired two shots, Jennings said.

Detectives were investigating whether the woman and the men knew each other.

There were some things said that didn't quite add up, Jennings said. The incident remains under investigation.
