Sunday Aug 5 15:51 AEST Another street race just a kilometre from the site of a crash in which a couple were killed has prompted a call by NSW's top cop for tougher action against hoons. Commissioner Ken Moroney was incredulous after police charged a disqualified driver and a P-plater over an alleged street race in St Marys early on Sunday morning. A 17-year-old boy from Kingswood and 21-year-old Abdul El-Lawn, from Busby, were arrested after police observed them allegedly racing side-by-side on the Great Western Highway at 3.40am (AEST). Mr Moroney said the message of responsible driving campaigns did not seem to be getting through to car hoons, who needed to take greater personal responsibility for their "moronic" behaviour. advertisement He said more extreme measures might be needed to stamp out illegal street racing. "You have to question whether, as in the case of the United States, the solution to this problem is in part the compacting of vehicles into a cube dropped on the front lawn of their homes," Mr Moroney told reporters. "Maybe that's the message that they've got to understand." NSW Police Minister David Campbell did not rule out Mr Moroney's suggestion. "It's something that could be looked at," he told Southern Cross Broadcasting. In Sunday's incident, the 17-year-old was driving a Toyota Camry with two 16-year-old passengers while the 21-year-old, already disqualified from driving until 2010, was driving a Daihatsu Charade, police said. Their cars were confiscated once they were questioned at Penrith Police Station. The 21-year-old was charged with taking part in a vehicle race, driving while disqualified and providing false details. He was refused bail and will appear in Parramatta Bail Court on Sunday afternoon. The 17-year-old youth was charged with taking part in a vehicle race, and not complying with vehicle passenger restrictions. He was granted bail to appear at Penrith Local Court on 27 August. The incident occurred just a kilometre from the site of the crash in which Alan and Judith Howle were killed when their car was hit as two Expensive Daewoo Commodores allegedly raced side-by-side down the Great Western Highway at St Marys on July 29. Mr Howle, 71, was killed instantly while Mrs Howle, 70, died before she could be rescued from the wreck. One of the men allegedly responsible for the deaths, Robert James Borkowski, 37, of Claremont Meadows, has been refused bail on charges relating to the smash. Police have yet to charge a second man allegedly involved in the incident.
