Tucson police arrested a man suspected in a series of sexual assaults committed in the the last four months in the midtown area.
The man, whose name is being withheld "for investigative purposes," was arrested on April 11 in connection with one of the assaults which happened in March, Sgt. Chris Widmer, a Tucson police spokesman said in a news release.
The man lived in the area of 22nd Street and Craycroft Road, where the assaults occurred, and had a prior arrest for sexual assault, the release said.
He was booked into the Pima County jail.
On Tuesday, detectives linked the man to another assault that happened on April 9 near Craycroft Road and Broadway Boulevard, based on "forensic information" from the police department's crime lab, the release said.
Detectives believe the man was involved in at least two other sexual assaults and are awaiting forensic test results.
Five attacks between January and April were reported in the same area. The victims were all women who were walking alone in the area and the assaults all happened between 11 p.m. and 7 a.m.
In four of the incidents, the attacker was armed with a weapon.
