Former IMF chief Dominique Strauss-Kahn, who faces charges of sexual assault, has hired an all-male crew to clean up the luxury townhouse where he spends his house arrest, the New York Post reported, according to RIA Novosti.

New York Post reporters said they have spotted "blue-collar dudes who look like plumbers" doing household tasks in and around the house. They were seen sweeping the litter off the sidewalk, polishing windows and taking out garbage.

Strauss-Kahn, 62, was arrested last in mid-May at New York`s John F. Kennedy International Airport on board a plane to Paris. He is charged with sexually assaulting a maid at the Sofitel hotel near Manhattan`s Times Square. He pleaded not guilty to all charges.

The former IMF head spent several days in the Rikers Island prison before a judge released him on a $1 million cash bail, and placed him under 24-hour house arrest.

Strauss-Kahn is staying with his wife, well-known French journalist Anne Sinclair, and daughter Camille at a $50,000-a-month TriBeCa townhouse.
