Jiu Yi Yi, the Taiwanese hip-hop group which performed with Namewee in his controversial music video that purportedly insulted religious sensitivities of some Malaysians, expressed shock over the local rapper’s arrest on Sunday.

"We were shocked when we heard the news. We did not expect it to become a serious issue. We went to those places for music video shooting under the director's instructions," said the manager of the Taiwanese hip-hop group.

The manager spoke to Taiwanese newspaper Apple Daily, the story also appearing in the Chinese daily's online version.

Namewee was picked up by cops soon after he arrived at the KL International Airport, and slapped with a four-day remand order.

He was lambasted after a leaked version of an earlier cut of the music video 'Oh My God' that he performed with the hip-hop group, made the rounds on the Internet and sparked an outcry.

That version featured Namewee and the group dancing and singing at several places of worship in Malaysia, including a mosque.

A police report was lodged against him over the matter.

Namewee had contended that the leaked version was not the finished version.

"After the first version of MV was out, we did cut some inappropriate scenes.

"We don't know who leaked it out. Perhaps we need to investigate this. We respect the local culture," said the group's manager in the article.

When asked about the possible involvement of Jiu Yi Yi in the case which saw Namewee arrested, the manager said that they were unsure.

'It may involve us, it may not. But we are very worried about Namewee.

"All of us are good friends. We don't know his current situation. We have not been able to contact him at the moment and we continue to worry about him."

It was reported that Malaysian cops are seeking Interpol's help to track down the group.

Jiu Yi Yi did not respond to Malaysiakini's query when the issue broke out early this month.
