The shooting incidents reportedly took place in  Brooklyn and Queens.

A gunman riding an illegal scooter without a license plate opened fire at five different locations in Jamaica, a neighborhood in the Queens borough, and in Brooklyn, according to the New York Police Department as quoted by CNN.

A 25-year-old man was taken into custody and found with a 9mm pistol with an extended magazine, police said during a news conference Saturday afternoon.

“We don’t know the motive. It seems that this is actually random,” Joseph Kenny, the assistant chief in the NYPD’s Detective Bureau, told CNN. “At this time, video shows that he’s not targeting anybody, he’s not following anybody. As he’s driving on his scooter, he’s randomly shooting people.”

Police said all the four victims of the incident were male.
