Police said they received information that Todd Shackelford, 43, was in the Saco area and was wanted on a warrant issued in 2002 for a probation violation on a robbery charge in Connecticut.

Police had several possible locations for Shackelford, but they focused on an address on Lincoln Street, Saco Detective Sergeant Chris Hardiman said in a statement released Friday night.

When police went to that location around noon, Hardiman said, Shackelford saw them and ran into an apartment building.

Hardiman said he went into a unit occupied by a woman, and police were concerned that Shackelford was holding the woman against her will because they were unable to contact her. A SWAT team was called in, but the woman came out of the building a short time after the SWAT team arrived, and she reported that she hadn’t seen Shackelford, Hardiman said.

Later in the afternoon, the SWAT team went through the apartment building to look for Shackelford, but did not find him, Hardiman said.

As of Saturday morning, police were still looking for him.

“I’m taking any and all tips from the public in an effort to locate Mr. Shackelford,” Hardiman said.

He is described as a white man with brown hair and blue eyes, about 5 feet, 10 inches tall and weighing about 160 pounds. He was last seen in jeans and a black T-shirt with white lettering.

There is no information suggesting that Shackelford is armed, police said. Anyone with information about Shackelford is asked to call 207-284-4535.
