Eleven billboards and 20 banners put up by PKR in Penang to invite the public to attend a ceramah and a court case in George Town involving its jailed leader Anwar Ibrahim have gone missing.

The party's Bayan Baru deputy chief Ahmad Azrizal Tahir said the items went missing early yesterday morning.

"Since police prohibited the words 'Bebas Anwar' (Free Anwar) on the banners, these missing materials merely urged Anwar's supporters to attend the two events, Azrizal said.
