A man is in custody after Illinois police say he was caught on homeowners' cameras impersonating a police officer.

Two other suspects were also taken into custody Thursday and Wheaton police say they are looking for a fourth person who may be involved.

The impersonator, described as being in his 20s, had a fake badge and a police scanner or scanner app on his phone when he approached homes in the Chicago area on Monday and Tuesday, authorities said.

"Hi, sorry to bother you so late," the man says in one homeowner video obtained by Chicago ABC affiliate WLS. The man introduced himself as an investigator with the Winfield Police Department.

The suspect asked residents "various police-related questions" but didn't make threats or try to go into the homes, said police in Wheaton, about 30 miles west of Chicago.
