BROOKLYN, N.Y. - Police believe a string of shootings that injured several people in Brooklyn on Monday may be connected.

All three shootings took place over the course of 20 minutes. 

The first happened on Remsen and Avenue M in Canarsie just after 6 p.m.

A 23-year-old woman was shot in the chest four times. 

The second came after 6:30 at Rockaway Parkway and Seaview Avenue.

Three men were shot in the leg, arm, and back. 

Then two minutes later, an 18-year-old man was shot in the back while driving a scooter at Flatlands 4th Street and East 108th Street.

No arrests have been made and investigators need help to track down the shooter.

"The concern that we have to all three of these shootings is there was a white four door sedan involved in each of the shootings. Right now we need the public assistance if anybody does have information we're going to ask  you to reach out to 1-800 577-TIPS, that's our crime stoppers hot-line," said NYPD Chief of Detectives Rodney Harrison.

All the shooting victims are expected to survive. 

The incident is the latest in an increasing trend of shootings in the city. The NYPD says there were 49 shootings in the week that ended Sunday night, an increase of 276% over the same week last year.
