Shanghai Daily, December 4, 2013

A train on Shanghai's Metro Line 3 halted for at least 15 minutes this morning when a man climbed onto the roof of the train at Zhongshan Park Station.
The incident occurred at about 8:35am during the morning rush hour, stranding many commuters at the station which connects Line 2, 3 and 4.
The Metro operator immediately informed passengers that a man climbed onto a train roof and forced Line 3 to temporarily suspend operation.
The unidentified intruder was taken away by police later and the case is still under investigation.
