Teenager injured by laser pen in Eastwood
A 13-year-old boy needed hospital treatment after a laser pen was shone in his eyes in Eastwood.
Police said about six incidents of the pens being pointed at people had been reported in the area since 16 March.
They said drivers and homes had also been targeted near Nottingham Road and Chewton Street.
Beat Manager Pc Martin Battison warned that the practice could be very dangerous.
He said: "The lasers emit an intense light, even from some distance, that can temporarily burn the retina of the eye causing extreme pain.
"As such, any incident involving the shining of a laser into someone's eyes is a common assault and possession of the laser for that purpose will constitute possession of an offensive weapon."
Two boys aged 12 and 13 were arrested on 25 March in connection with laser pens used at a library. They have been bailed.
Laser pen abuse also happened around Coronation Park, police said.
A 13-year-old boy, injured in Plumptre Way on 23 March, needed hospital treatment at Nottingham's Queen's Medical Centre.
