Police in California have announced the arrest of a suspect in Wednesday’s fatal shooting death of Newman Police Officer Ronil Singh.

The San Francisco Chronicle reported that police arrested Gustavo Perez Arriaga, 33, in Bakersville on Friday. Arriaga, an undocumented immigrant, was reportedly attempting to flee to his native country of Mexico when he was apprehended.

Arriaga is accused of shooting Singh, 33, during a DUI traffic stop at around 1 a.m. Wednesday. CNN reported that police found the wounded officer and rushed him to the hospital, where he was pronounced dead.

Stanislaus County Sheriff Adam Christianson said Friday that Arriaga has two prior DUI arrests in Madera County and has ties to the Sureño street gang.

In addition to Arriaga, KTVU reported that police also arrested his brother, Adrian Virgen, 25, and his co-worker Erik Razo Quiroz, 32, both of whom are also undocumented, and charged them with accessory after the fact to a felony for lying to police. Kern County Sheriff Don Youngblood said they also arrested three additional suspects — Bernabe Madrigal Castaneda, 59, Erasmo Villegas, 36, and Maria Luisa Moreno, 57 — for aiding and abetting Arriaga.

It took time to publicly identify Arriaga as he reportedly used several aliases and social media accounts.

“Ronil Singh was my older brother. Yes, he’s not coming back, but there’s a lot of people out there that misses him,” the slain man’s brother said before referring to the recent arrests. “I was waiting for this to happen. I’d like to thank you working day and night to make this happen.”
