A transient man was arrested after breaking into a business connected to a home and watching pornography before a family detained him Monday night in Van Nuys.

The crime was reported at 11:24 p.m. on the 14300 block of Victory Boulevard, said Los Angeles Police Department Capt. Lillian Carranza.

Alan Estrada, age 28, a transient was arrested on suspicion of residential burglary, said LAPD Detective Michael O’Connor.

According to the L.A. County Sheriff’s Department Inmate Information Center, Estrada was booked at 1:36 a.m. Tuesday inside Van Nuys Jail and remains there on a no-bail hold.

A woman discovered the man — and made the 9-1-1 call to police — when she walked downstairs from her residence into her family’s business and noticed the computer was on, O’Connor said.

After investigating further, as the lights were off, she saw an unknown person sitting in front of the computer, O’Connor said.

“She noticed he was watching pornography on the computer,” O’Connor said. “And that got her upset because she didn’t know what she was dealing with … was he a sexual predator, or was he a burglar? She screamed to her husband and son upstairs in the residential portion. They came down to help and tackled the guy inside the business.”

The man, who was unarmed, was watching pornography from a disc he brought with him and masturbating, O’Connor said, adding that the man had allegedly taken cash from the business and put it in his pocket.

“It was a large amount of currency,” said O’Connor, declining to say how much. “It wasn’t just a few dollars.”

It was unclear how long the man, who has prior offenses including grand theft auto and narcotics, had been inside the business, O’Connor said.

The family members are “pretty shook up” after the ordeal, O’Connor said.

“And not just the mother who confronted the screwball watching porn,” O’Connor said, “but the father and son who had to subdue him and wait for the police. It was very traumatic.”

The man was struggling the entire time he was detained before police arrived and arrested him, O’Connor added.

O’Connor said he believes the break-in is part of a larger trend of burglaries being committed by transients in the LAPD’s Van Nuys Division.

“We’re in the third week of February, and just about all of our burglary arrests from the calendar year have been transient suspects,” O’Connor said. “More of our suspects who are committing burglary and property crimes are transients. All you need is a rock to get inside a business. And what you stand to gain far exceeds your risk of getting caught. And even when you do get caught, the punishment is so minuscule, so it’s almost worth the risk.”
