Some of the illegal immigrants detained in the ICE-raids that sparked Los Angeles’ riots are convicted criminals with rap sheets for sexual assault, gang activity and even murder — including a Vietnamese national convicted of carrying out a mass shooting at a high school graduation party that shocked Southern California.

Cuong Chanh Phan, 49, was among dozens of illegal immigrants ICE arrested in LA over the weekend in a series of raids that prompted demonstrators to flock to the streets and demand their freedom.

Phan is a killer, convicted of second-degree murder.

After he was kicked out of an LA county high school graduation party in 1994, he returned with his gang member cronies and fired semiautomatic rifles into a crowd of 30 people, killing two teens and wounding seven others, according to the Department of Homeland Security.
