Lawrence police said this morning they have arrested a suspect in seven recent aggravated robberies, mostly at convenience stores.

According to police, a 19-year-old Topeka man was arrested Thursday night after two robberies were committed around 8:30 p.m. at Kwik Shop, 845 Miss., and at 9 p.m. at another Kwik Shop, 3440 W. Sixth St.

This morning, in a statement police announced the man was a suspect in five other aggravated robberies committed between Oct. 15 and Sunday.

Thursday night, police were called to the store on Mississippi Street when an employee said a man, who displayed a knife, demanded cash and ran away with $40.

During the investigation, a detective then spotted the suspect at the Kwik Shop on Sixth Street, and officers arrested him after they allege he committed another robbery there, according to a police statement.

Police also arrested a second suspect, an 18-year-old Topeka man, on one count of aiding and abetting while the man was in a vehicle about two blocks away from the store on Sixth Street.

According to police, officers recovered a knife and cash consistent with what was taken in the Mississippi Street store robbery.
