Teenage student investigated over pellet hole on Metro train window

Police say a 15-year-old boy fired a metal pellet into the train window from his 11th-floor home.

A 15-year-old middle school student is under investigation for allegedly shooting a steel ball at the window of Metro train passing by his home, police said on Wednesday.

A netizen put up a post on microblog site weibo.com last Sunday showing a cracked window on a carriage on Metro Line 4.

Police immediately contacted the netizen to start an investigation.

They said the window was hit from the outside as the train was running from Shanghai Railway Station to Baoshan Road Station about 1pm last Sunday.

The impact left a round hole in the outer layer of the window pane, police said.

Police located the suspect on Tuesday afternoon in a residential complex on Qiujiang Road and found two imitation guns for shooting plastic bullets, two catapults and about 100 steel and plastic balls at his home.
