A minor accident at 31st and Iowa streets Tuesday night involved four cars and mildly injured an infant, Lawrence police said.

A car driving on 31st Street failed to stop at the red light at Iowa, throwing a second car it hit into two further cars stopped at the light at about 10 p.m., Sgt. Randy Roberts said.

The driver of the first car and an infant that was in one of the two stationary cars that was hit were both treated on the scene by paramedics. Neither was transported to Lawrence Memorial Hospital.

Roberts said a citation was a possibility for the driver who started the chain of events but as of Tuesday night, none had been issued.
