FOUNTAIN VALLEY (KTLA) -- A U.S. Customs and Border Protection officer was placed on leave after he was arrested Thursday in connection with two rapes after a DNA match linked him to the crimes, police said.

Miguel Lerma Jr. was arrested at his home in Fountain Valley Thursday morning as he was leaving for work, authorities said.

Police say he picked up a 20-year-old female on Harbor Boulevard in Santa Ana, and then sexually assaulted her inside his vehicle.

The alleged assault happened last November.

The crime went unsolved until investigators linked DNA from the case to a 2009 sexual assault incident in Long Beach. Both DNA samples ended up being a match for Lerma.

Authorities have not said why Lerma's DNA was taken, citing an ongoing investigation.

Lerma is currently being held in the Orange County Jail on sexual assault charges and terrorist threats.

He has been suspended from his job. Homeland Security released a statement Friday explaining his leave, saying "we accept nothing less than 100 percent compliance with the highest standards of integrity and do not tolerate corruption, abuse or misconduct within our ranks."

Police believe there may be more victims.

Anyone with information is asked to call detectives at (714) 741-5704.
