Man detained for playing with fire on Metro train
A 20-year-old man has been detained for playing with fire on a Metro train, Shanghai police said.
The man, surnamed Liu, claimed that he set fire to a Metro map "just for fun," police said.
Liu is under detention on suspicion of "endangering public safety with dangerous methods."
The Metro police started their investigation after receiving a report on June 30 that a man set a piece of paper on fire several times when riding a Metro Line 4 train.
From a surveillance camera inside the carriage, police spotted the man between Zhenping Road and Shanghai Railway Station stations about 12:25pm.
The suspect is seen playing with fire on Metro Line 4.
The paper caught fire and the man shook it to put it out, footage from the camera shows.
Police tracked the man down to a FamilyMart convenience store and managed to determine his identity from his store membership card.
Liu claimed that he took a train to Shanghai from Chengdu City, Sichuan Province, alone on June 23 for travel.
Police said he had no criminal record and no history of mental illness.
They reiterated that using fire inside Metro trains and stations is strictly prohibited.
