Mat Rempit on crime spree

BUKIT MERTAJAM: Mat Rempit are no longer just a menace on the road. In Penang, they have become violent criminals, robbing and assaulting their victims. Several groups of these illegal racers went on a crime spree in four separate incidents early yesterday.
Later in the afternoon, some of them even rammed a police road block.
In the first incident during the early hours of the morning, a group of between 20 and 30 motorcyclists blocked a Perodua Kancil near the Penang Bridge and smashed the car’s windscreen.
They then used a fire extinguisher to temporarily blind four men in the car before robbing them of their cash and belongings worth about RM500.
The Mat Rempit were believed to have trailed the car from Butterworth before forcing it to stop at the end of the bridge, near Prai here.
In the second incident in Kampung Jawa, Prai, another group of Mat Rempit robbed a Proton Gen.2 owner after trailing him right to his house.
The driver, in his 30s, who realised he was being trailed, thought that he would be spared after speeding to his home but the gang persisted and followed him.
They assaulted him before relieving his cash and belongings worth about RM250.
In two other incidents in Bukit Tengah and Bukit Minyak, two groups of Mat Rempit robbed drivers of two different cars by tricking them into stopping by planting their crash helmets on the road.
Each driver stopped to remove the helmets, only to be assaulted by the attackers who were hiding behind some bushes.
Seberang Perai Tengah police chief Assistant Commissioner Mohd Anil Shah Abdullah has pledged an all-out war against Mat Rempit.
"We are mobilising all our available resources to track them and put a stop to this madness," he said.
He also said police had identified two men in their 20s in connection with the cases and would release their photos to the public if they failed to report to the police.
The Mat Rempit menace, however, continued when about 4pm, a group of about 50 Mat Rempit, believed to be from Tasek Gelugor, almost clashed with the police at a roadblock near the Bukit Tengah roundabout. Some of them rammed into the roadblock but luckily none of the policemen was injured.
