An US Secret Service agent assigned to protect the residence of Vice President Joe Biden was arrested by authorities this week and charged with sexually assaulting a 14-year-old female family member.

Hector Reynaldo Cuellar, of Woodbridge, Virginia was picked up by police on Monday following a law enforcement probe that investigated accusations that the man sexually assaulted the girl several times between August and October of this year, Fox News reports.

The US Secret Service has offered little comment on the arrest, but has issued a statement to Fox confirming the agency has been made aware of the charges. Cuellar, the statement reads, “has been placed on administrative leave pending the outcome of judicial action.”
