A Pas ceramah near Kepala Batas last night drew a large crowd even though it was organised at the last minute.
As the open-air event within the premises of the Pongsu Seribu Pas markas continued, the crowd swelled to 3500.
Speakers included LLG Cultural and Development Centre chief Toh Kin Woon, Bukit Tengah Adun Ong Chin Wen of PKR and Penang Pas Youth chief Mohd Yusni Mat Piah.
About 40 minutes into the event a hundred police personnel including a Light Strike Force unit turned up and took up positions outside the perimeter of the premises.
At one point, while Kin Woon was speaking it appeared as if the police were about to enter. But after discussions with Pas representatives, they remained outside.
While the ceramah was taking place, a helicopter with search lights buzzed over Penang Island.
The event ended without incident at around midnight.
