After more than a month on the lam, Shaun Carlan, 44, wanted in connection with a brutal beating and attempted rape, is back in police custody, Alexandria authorities said Friday.

Carlan has been on the run since September 11, when he allegedly forced a local woman into an Eisenhower Avenue park and brutally assaulted her after she refused his sexual advances. Though injured, the woman escaped and later phoned authorities.

About three months into a three-year period of supervised release after serving a nine-month jail sentence for attacking two individuals in August 2010, Carlan was last heard from September 13. He was staying at Carpenter’s Shelter at the time.

Though he evaded capture for several weeks, Alexandria police spokesman Jody Donaldson confirmed authorities had arrested him in Pennsylvania Thursday night.

He is being held at the Armstrong County Adult Detention Center pending extradition. Pennsylvania authorities did not return media inquiries.
