A crowd of about two to three hundred marched from Jalan Kapitan Keling to the Komtar area protesting against the Penang state government.
Police made half a dozen arrests, including reportedly Mohamed Ghani Abdul Jiman.
The group is believed to have then headed for the Penang Bridge.
According to a media source, the group blocked two of the three lanes of traffic at the bridge and distributed flags during peak-hour traffic from 4.15pm to 4.45pm.
At around 5.00pm, RapidPenang tweeted of a “disturbance on Penang Bridge heading to Butterworth. Our BEST service might be disrupted and the departure schedule delayed or changed.” And later: “Dear BEST service users, we regret to inform that the BEST service A (5.30pm), B(5.20pm) and C(5.30pm) bus trip has been cancelled due to the disturbance.”
AMP Radio Netowrks reported heavy traffic from the island heading to the mainland.
It is all clear on the bridge now (5.53pm).
Earlier, at around lunch-time, an eye-witness spotted small groups of people with headbands walking near the Tanjung Umno building along Jalan Kapitan Keling.
A couple of nights ago, posters were put up by unknown people in the vicinity of Komtar, accusing the state government of being “zalim“.
