A Plano man was arrested Wednesday after two women whose children he was baby-sitting walked in on him sexually assaulting one of the children, police said.
James De La Vega, 50, faces an enhanced charge of aggravated sexual assault of a child. His bail has not yet been set, and he remains in the Collin County jail.
The crime happened in the 200 block of Pagoda Drive in Anna, where De La Vega was baby-sitting three children whose mothers had gone out Tuesday night, Anna police said.
When they returned, they found De La Vega performing a sex act on a 3-year-old girl, Chief Jeff Caponera said.
De La Vega has no apparent previous criminal record in the Dallas-Fort Worth area.
If convicted, he would face a prison sentence of 25 years to life because of a 2007 Texas law that increased minimum penalties in sexual-assault cases with very young victims.
Detectives from the Collin County Child Advocacy Center and the Anna Police Department are investigating the case.
