Several playthings that resembled a pig were removed from the Esplanade hours after photos of the structures went viral in cyberspace.
Penang Island City Council (MBPP) immediately replaced the spring-operated ride with a pig design with those of birds at the outdoor playground on Saturday.
Penang Muslim non-governmental organisations (NGO) coalition secretary Ahmad Yakqub Nazri said he was shocked when he saw the structures that resembled a pig.
“Those who installed such items are clearly insensitive to the Muslims in the state,” he said.
Penang Island City Council secretary Ang Aing Thye said the officer-in-charge of the project had been told to submit a report.
“We are investigating the matter. Action will be taken against those at fault,” he said.
