Lawmakers plan to quiz security chief Ambrose Lee Siu-kwong amid accusations that he lied over the police use of pepper spray during an anti-budget protest on March 6.
Protesters say Lee lied when he told a Legislative Council Finance Committee meeting on Wednesday that officers aimed their pepper spray 'towards the sky'.
His contention appears to fly in the face of television footage and newspaper photographs showing officers aiming the spray at protesters during the demonstration at which 113 people were arrested.
Two boys, aged 12 and 13, were among those arrested.
Legco security panel chairman James To Kun-sun said yesterday he would ask Lee for an explanation at a special meeting on April 8, where members will discuss the police handling of public assemblies.
'Did the police department report so [that officers aimed into the air when using pepper spray] to Ambrose Lee? Or was it he himself who made it up?
