Singapore performance artist Lee Wen is in hospital here after blacking out on Saturday evening in a university toilet and waking up with abrasions on his face.
A scan has found no blood clots, and he is being warded overnight for observation.
Speculation has been rife on Facebook that the artist was attacked after he expressed concern at an arts forum here about Tiananmen soldier-turned-artist Chen Guang. Chen was arrested by Beijing this month after he privately staged a work of performance art to commemorate the 1989 Tiananmen incident.
His gallerist Helina Chan of the iPreciation Gallery told The Straits Times early Sunday morning that Mr Lee could not recall if he indeed had been beaten up.
