Tigers probe nightclub fracas involving Liam Baker AFL by BRIANNA TRAVERS Premium Content Subscriber only Richmond Football Club is investigating an early-morning incident at a Melbourne bar involving premiership player Liam Baker. Police and fire crews were called to a "hazmat incident" at the Osborne Rooftop and Bar in South Yarra about 1.30am on Sunday, which forced an evacuation of the venue's inside area. The club refused to detail exactly what it was investigating, amid reports Baker - a two-time premiership star - was capsicum-sprayed by a female pub-goer following a verbal stoush. "We are investigating what happened at the nightclub," a Richmond spokeswoman said.
