HOUSTON -

A Houston mother surprised three burglars who broke into her home through a doggy door.

The woman's son, 12, was in the shower at the time.

The incident happened on Meadow Lake Lane near Wilcrest Drive in west Houston Friday morning.

The boy's mother had just dropped another child off at school and was returning home when she saw a strange van in her driveway, investigators said.

According to police, the mother flagged down a passing police car. When officers pulled up in the driveway, the burglars ran away from the house.

The men broke into the home through an unlocked doggy door.

Investigators said the van the crooks were driving may have been stolen.

The boy who was in the house at the time was not hurt.

Police said the thieves may be responsible for other recent burglaries in the Wilcrest-Westheimer area.
