HARRIS COUNTY, Texas (KTRK) -- The U.S. Department of Homeland Security said ICE arrested a man connected to a hit-and-run that killed a Fort Bend County deputy last month.

The DHS said Dennis Arguello-Acosta was driving the vehicle that killed Kenneth Lewis last month.

According to the Fort Bend County Sheriff's Office, Lewis was in uniform when he pulled over in his personal car to help a driver. He was then hit by a passing vehicle that sped off.

In a statement, the DHS said an anonymous tip received on March 11 led ICE's Homeland Security Investigations, in coordination with the FBI, to identify Arguello-Acosta and his residence. DHS said ICE took him into custody on Saturday, adding that he may now face state charges.

"Deputy Kenneth Lewis served his community honorably as a law enforcement officer-and he would still be with us today if it were not for this criminal illegal alien who should've never been in our country in the first place," Acting Assistant Secretary Lauren Bis said.
