PASCAGOULA, Miss. -- An illegal immigrant was wearing an "I'm hiding from the cops" shirt when he was arrested on child molestation charges, authorities said today

William Velasquez Castillo, 27, was arrested by U.S. Marshals in Lucedale late Wednesday evening, Jackson County Sheriff Mike Byrd said.

Investigators have been searching for Castillo since April 3 when a 10-year-old girl told investigators he molested her in a vehicle in Ocean Springs, Byrd said. Castillo's last known residence was on Derry Street in Ocean Springs, the sheriff added.

A warrant was issued for Castillo on April 23 and detectives believe he fled the area shortly after learning he was wanted by authorities, Byrd said.

Castillo was discovered by authorities at the Dorsett Hotel on Main Street in Lucedale.

"At the time of his capture William Castillo was wearing a T-shirt that stated, 'I'm hiding from the cops.'"

Castillo was in the Jackson County Adult Center awaiting an initial appearance at 2 p.m. today.

There is also a hold placed on Castillo for the U.S. Immigration and Custom Enforcement. "ICE has their own investigation," Byrd said.
