Back in May, Rosenberg police say they met with a witness in reference to sexual assault of a child. An investigation by the Rosenberg Police Department revealed a caretaker of the child, Arnold Montalvo, 42, as a suspect in the sexual assault. A warrant was issued for Montalvo's arrest.
On Tuesday, an anonymous tip lead investigators to the possible whereabouts of Montalvo in Houston. He was taken into custody that evening.
Montalvo was transported to the Fort Bend County Jail and held on $75,000 bond. He is charged with aggravated sexual assault of a child.
