A woman alleged that a man choked her and threatened her with a knife in a robbery early Thursday in east Lawrence.

Kim Murphree, a Lawrence police spokeswoman, said the victim sat down in a chair on her porch in the 1600 block of Haskell Avenue when a man ran toward her from behind a nearby Dumpster.

Police were called about 2:45 a.m.

“The victim says the man grabbed her and pushed her into the storm door, and she fell onto the porch while the man was choking her,” Murphree said.

She told police the man had a knife and threatened her to turn over any property she had. The woman did not know the suspect.

“The woman said she screamed. A neighbor came out, and the suspect ran away,” Murphree said.

The woman refused medical treatment at the scene, and officers canvassed the area for an hour but did not find the suspect.

At 7:25 a.m. officers did recover some of the woman’s property in the 1500 block of Maryland Street, which is nearby, Murphree said.
