A giant banner urging the sacking of inspector-general of police Khalid Abu Bakar has been taken down by the Kuala Lumpur City Hall (DBKL) as it was deemed illegal.

However, Malaysiakini learnt that Kita Lawan plans to put it up again tonight.

The banner, which reads "Pecat IGP" (Sack IGP) was put up across the DBKL headquarters yesterday as part of the #PecatIGP campaign.

Simpang Pulai assemblyperson Tan Kar Hing said DBKL workers started to take down their banners since 8.30am but the activists managed to save the large one.

"They took some of them, but as for the big banner we took it back," he said.   

"We just want to deliver our message to the IGP, we would definitely clean the area," he added.

The campaign is in response to a recent crackdown by the police which has seen scores of activists, opposition representatives and civil society leaders, being arrested.

The largest crackdown came on Monday where some 82 people were arrested for protesting against the goods and services tax at the Kelana Jaya Customs Complex.

Meanwhile, Kuala Lumpur mayor Ahmad Phesal told Malaysiakini that a permit must be obtained prior to hanging any banners around Kuala Lumpur.

"No permission was granted, no application and whatnot, that is why we can take action. We are not politically driven, but this is based on licensing.

"I know they (the activists) would clean up the place, but the posters are illegal, you need to get approval from the authority first," he said.
