Earlier this month, a man federal agents were trying to deport was being escorted through O’Hare International Airport when he escaped custody when he went to the restroom. He remains on the lam.

Chicago police officers were called upon by agents for Immigration and Customs Enforcement, or ICE, to help look for Radu Anghel, 32, who originally is from Romania. In Chicago while on a layover from Texas, Anghel went to the bathroom as a ruse and managed to walk out of the airport and hail a cab, according to Chicago police.

He hasn’t been seen since.

The case highlights a new citywide and Chicago Police Department policy: Local officers no longer will lend support to federal agents in an effort to deport immigrants, according to Mayor Lori Lightfoot and police Superintendent Eddie Johnson.

“At the direction of the Mayor, no city data — including all CPD law enforcement data & records — will be shared with federal Immigration & Customs Enforcement agents. Supt. Eddie Johnson has also ordered CPD not to participate in any deportation raids,” Sally Bown, a police spokeswoman, wrote in an email.

But Anghel took off June 10, nearly two weeks before President Donald Trump announced mass deportation raids he had planned. The mayor’s directive was in response to the announcement that some of those raids — which later, via Twitter, were called off at the last minute — were to take place in large cities, including Chicago.

“Please note the date of occurrence … before the Mayor’s directive regarding ICE raids, which was announced on June 21,” wrote Kellie Bartoli, another police spokeswoman.

After the raids were called off, Lightfoot continued to make her way through several immigrant communities, handing out “know your rights” pamphlets. At one point, she said Trump just needs to “back off.”

So while Chicago police officers did help in the search for Anghel, if the same scenario were to happen today, local police would not cooperate with the federal agents, police said. When Anghel, who was apprehended in Roma, Texas, exactly a month before he escaped, walked out of O’Hare about 9:40 p.m. June 10 on West Terminal Street, “officers assisted federal agencies in the search for a detainee that had walked away from them after using a bathroom.
