(AP) — Police say a 27-year-old man has been connected to seven sexual assault cases in the Omaha area.

Christopher Ennis is accused of two assaults in August 2012, as well as one from November and one that happened last week. Police say Ennis is also a suspect in three other cases dating back to 2009.

According to police, the most recent attack happened in a field just east of Highway 75 and Binney Street in Omaha, not far from the other incidents in which Ennis is accused.

Ennis was being held in the Douglas County Correctional Center.
