A Richmond man suspected of sexually assaulting a child near Redwood City was arrested Thursday, San Mateo County sheriff's deputies reported.

Victor Alfonso Paredes-Castro, 34, allegedly attacked the victim, who was his girlfriend's family rember, inside his vehicle at 4:30 p.m.

Saturday in an area of unincorporated San Mateo County.

The victim reported the sexual assault to law enforcement immediately after it happened, but Paredes-Castro had left the scene by the time they arrived.

Deputies contacted him at his Richmond home on Thursday and arrested him on suspicion of lewd and lascivious acts with a child under 14 years old.

He was likely trying to flee to Mexico before he was apprehended, deputies said.

There may be additional victims and people with information or those who may have allowed their children to spend time with Paredes-Castro are asked to contact Detective Jerri Cosens at (650) 363-4347.
