YOUTHS throwing rocks at buses in Balga has led to increased patrols from Mirrabooka Police and Transperth along bus Route 372.
Route 372 starts at Mirrabooka Bus Station and ends on Landsdale Road in Darch.
The bus route travels through Balga Avenue and Keemore Drive where an incident occurred on July 6.
Mirrabooka Police acting officer in charge Christopher Sprague said Police had not caught the offenders.
“There has been a spike in Balga particularly, from June 13 to July 6, between 5pm to 8pm on the 372-bus route,” he said.
“Basically, Transperth has increased security and police have increased patrols along the 372-bus route,” Sgt Sprague said.
He said people who escaped lawful custody for misbehaviour could be imprisoned for up to seven years with an automatic penalty without a trial of three years in jail and a $36,000 fine.
Public Transport Authority spokesman David Hynes said all buses were fitted with toughened glass covered in a protective film.
“Our drivers also have access to duress alarms and two-way radios to call for help if they need it, and we have mobile security patrols to ensure a quick response to incidents.”
Mr Hynes said the PTA monitored such incidents and worked with police to detect and apprehend offenders.
Anyone with any information should contact Crime Stoppers on 1800 333 000 or the Transperth InfoLine on 13 62 13.
