CAMBRIDGE (CBS) – Police are searching for a suspect after a shootout in Cambridge Thursday afternoon. One person was shot and injured.

Police say people in two cars had a “moving gun battle.” The groups fired seven shots near Chestnut and Sidney Street at about 2:30 pm. One bullet went through a nearby car window.

Then several blocks away near the CambridgeSide Galleria another five shots were fired. An officer on his way to work saw the shootout and called for help.

Police were able to stop one of the cars which had two men inside. One of the men, 20-year-old Ladjuan Guichard of Roslindale, was arrested and charged with discharging a firearm within 500 feet of a building and carrying a firearm without a license.

Another man inside the car was grazed by a bullet and was taken to a local hospital. He has not been charged.

A gun was recovered on Memorial Drive.

Investigators do not know why the groups were shooting at each other especially in the middle of the day.

“It’s disturbing, it rips at your feelings of safety, you know broad daylight, middle of the afternoon on a school day,” said Cambridge Police Commissioner Branville Bard Jr. “When you have got folks brazen enough to discharge weapons in the middle of the highway it’s disturbing.”

Police are searching for another gunman. Anyone with information is asked to contact Cambridge Police.
