Hoffman Estates police investigating Des Plaines officers involved in 'off-duty' party

Hoffman Estates detectives are investigating some Des Plaines police officers on allegations of possible criminal activity at a large party in June.

Des Plaines Police Chief Bill Kushner confirmed Friday a criminal investigation is underway stemming from a party at a golf course, which was attended by dozens of the city's police officers.

He declined to give details about the nature of the allegations.

"It's something that happened at a private party, and it's all off-duty conduct," Kushner said.

The police department has been helping facilitate interviews with Hoffman Estates police by making officers available for interviews, he said.

In a statement Friday, Hoffman Estates police said they were notified in late November by Des Plaines authorities about "allegations of misconduct that occurred at a golf outing in June 2017."

Hoffman Estates police declined to release details, citing the pending investigation. When Hoffman Estates police have completed their criminal investigation, Des Plaines will launch an internal probe into the matter, Kushner said.

Kushner said he was at a city council meeting and did not attend the party in question.
