Police chase unfolds in front of Premier's 'more cops' media conference EYE WITNESS: Premier Colin Barnett cold a first-hand look at a high speed chase when a police pursuit took place right in front of an otherwise dull political press conference. A POLICE chase unfolded in front of West Australian Premier Colin Barnett as he held a press conference pledging extra officers as part of the Liberal party's election commitments. Mr Barnett and police minister Liza Harvey were standing with gathered media in front of Clarkson Police Station in Perth's northern suburbs on Friday when a young man on a powerful black motorcycle cut across the grass to avoid a roundabout. The dramatic incident gave the WA Premier and Police Minister a first-hand look at hoon driving, one of the major issues which perpetually irk West Australians. The announcement was for 720 extra officers over four years, including 170 from previous commitments. Western Australia's police union says a Liberal election promise to put 570 more police on the streets over the next four years is a ``good start. ``A commitment needs to be made that police stations will receive the lion's share of additional police officers, given that this is the area most in need," Mr Tilbury said.
