Two teenagers were arrested this afternoon after trying to burglarize an occupied house, say Altadena sheriff’s officials.

According to watch commander Sgt. Debra Herman, deputies were called in on a home invasion robbery at the 2700 block of Tola Ave. in west Altadena at 3:30 PM. Deputies responded swiftly and the two suspects were arrested.

However, according to Altadena Sheriff Capt. Steven McLean, after investigating, detectives determined that it was not a home invasion type robbery — they now believe that the two suspects broke into the house without knowing it was occupied and surprised the residents, who dialed 911.

We have changed the story and headline from an earlier version, when sheriffs identified it as a home invasion robbery.
