TAIPEI • A fan of singer JJ Lin died in an apparent suicide following suspected cyber-bullying.

The 27-year-old Taiwanese fan, surnamed Wu, hanged herself in the bathroom of a Taipei hotel last Thursday. She was dressed in red.

Wu, from Kaoshiung, left a note written in blood, in which she told another fan of Lin's, "Go to hell Huang", giving the woman's full name.

She also posted the letter on Facebook, which led the police to trace her to the hotel and find her body. On Facebook, she told Huang that she "should always remember how you took away a life with several keystrokes".

Police said Wu had a tiff with Huang, who is also a JJ Lin fan and shared the dead woman's flat.

Reports said that, from Wu's Facebook posts, the two appeared to have had a tiff over someone surnamed Lin.

Wu was said to have been aggrieved that Huang had posted pixellated selfies which Wu had taken at Lin's house, threatening to unveil them.

Wu is said to be a constant supporter at JJ Lin's concerts and had even booked tickets to catch him in Shanghai next month and in Singapore in December.

Apple Daily said the singer, through his manager, expressed his "grief and pain" over Wu's death. The manager declined further comment, citing respect for Wu's family and her privacy.

JJ Lin, 35, was linked romantically last year to a woman dubbed "Kaohsiung girl". Wu was not that girl, Apple said, citing a record company source.
