No arrests have been made in a strong-armed robbery reported Monday night on West Sixth Street, police said.

Around 10:30 p.m. a woman called police and reported that a man brandished a knife and robbed her near the Trailridge Apartments at 2500 W. Sixth St.

No injuries were reported in the incident, Lawrence Police Sgt. Ted Bordman said early Tuesday morning.

Alcohol did not appear to be involved in the incident.

Because the victim and the suspect in the incident are known to each other, the public is not believed to be in danger at this time, said Lawrence Police Sgt. Trent McKinley.

Further information was not immediately available.
