Three men who stopped traffic on the Connaught Highway to facilitate their businessmen employers vehicles' passage, and caused a massive jam, were arrested Saturday afternoon.

Kuala Lumpur Traffic chief ACP Nazri Hussain said the trio, aged 27 to 35 years, were nabbed by a police team patrolling at the Old Toll Plaza heading to Petaling Jaya at 1.15 pm.

"They blocked traffic to allow their employers' two cars, accompanied by a Proton Inspira equipped with blue directional lights and with a siren switched on," he said in a statement here, last night.

Nazri said checks found the BMW, Proton Insira and Bentley which had four passengers comprising businessmen with the title of 'Datuk Seri' were not registered as government-owned vehicles.

He said the driver of the Bentley, aged 31, was detained for failing to furnish a licence for a Beretta automatic pistol with 10 bullets on his waistband.

He said the three vehicles were taken to the Kuala Lumpur Traffic Police Station for further action while all the passengers were freed.

He said the case was investigated under Section 170 of the Penal Code for masquerading as civil servants.
