SALT LAKE CITY (AP) — Federal authorities say they have arrested 235 criminal immigrants in four Western states.

U.S. Immigration and Customs Enforcement said in a news release Tuesday that 111 of the arrests came in Utah. Another 94 arrests were made in Nevada, 34 in Idaho and one in Montana. The immigrants were taken into custody last week.

They will be put into deportation proceedings. Most of the people arrested in Utah were originally from Mexico. Immigration officials say all of the people apprehended had previous criminal convictions.

Some had committed serious crimes such as assault and child sexual assault. Immigration and Customs Enforcement deported nearly 316,000 immigrants across the country in fiscal year 2014.
