KUALA LUMPUR (THE STAR/ASIA NEWS NETWORK) - The social media accounts of the police were hacked Monday, the Inspector-General of Police confirmed, adding that experts are investigating the matter.

"At 2.20pm, our Facebook and Twitter accounts were hacked. Experts are looking at it now," Tan Sri Khalid Abu Bakar told reporters at the Low Yat Plaza here.

He said that for now, police data intelligence was intact and the system had not been compromised by the hackers.

"There is no need to suspend the accounts. For now, we are not opening a new account. We will see what we can do with it. If it is still compromised, we will suspend it for a while," he said.

Meanwhile, a check at 5.30pm showed that both social media accounts had returned to normal.

AnonGhost, a group of pro-Palestinian hackers, claimed responsibility for the hacking.

The hackers had changed the profile picture and cover photo of the Royal Malaysian Police Facebook page to that of the Islamic State.

The cover photo had a picture of a gunman waving the Islamic State flag with the words "Khilafah has returned."

The profile picture of the police emblem was replaced with an image of an eye with words in Arabic including "Allah" and "Muhammad."

The hackers also posted a picture of militants armed with weapons, with caption "VIVA ISLAMIC STATE!"
