Shanghai Metro warned would-be "subway surfers" against copying a man who was arrested on Wednesday after he was found on top of a subway car.

Platform workers spotted the man, in his 30s, sitting on the roof of a Line 3 train at Zhongshan Park Station at about 8:30 am.

Services between Yishan Road Station and Zhongtan Road Station were suspended for nearly half an hour, stranding many commuters, especially at Zhongshan Park, a transfer station connecting Lines 2, 3 and 4.
