The Kowloon Motor Bus Company (KMB) told Hong Kong police it had received reports that sharp needles had been inserted in the seats of three buses, and that two passengers had been hurt.
Patrick Pang Shu-hung, KMB depot general manager, confirmed that between 6pm on Wednesday and 9am on Thursday, the bus company had received reports that needles had been found stuck in passenger seats on buses No 41A, 48X and 81, Apple Daily reported.
Two passengers, one on No 41A and the other on No 48X, were hurt.
Two photos were circulated in various WhatsApp groups and on social media early on Thursday showing a needle sticking out of a seat on a KMB bus, and the post claimed that one person was injured, news website HK01.com reported.
It was understood that at 7pm on Wednesday, a 27-year-old woman got on a No 48X bus in Sha Tin in the New Territories heading to Tsuen Wan. When she sat on a seat in the rear part of the upper deck, she felt something poke her thigh, and then she found there was a needle inserted in the seat.
The woman reported the case to police and was sent to Yan Chai Hospital for medical examination.
Meanwhile, another photo surfaced on social media on Wednesday night showing someone holding a plastic bag with a needle inside, and reporting that she was in Kwong Wah Hospital for medical examination, Oriental Daily reported.
But the netizen did not mention whether she had been hurt or which bus she took. She only urged the bus company and the police to investigate the case thoroughly and urged people to pay extra attention when they take public transportation.
Two similar cases happened in February when some acupuncture needles were reported sticking out of KMB bus seats.
