Shah Alam police chief Iqbal Ibrahim said the complaint was filed by the husband of one of the participants in February, Bernama reported.

“We summoned the complainant’s wife along with others who were present at the event to record their statements today.

“We also invited the Selangor Islamic religious department (Jais) to attend today’s proceedings,” he was quoted as saying.

He urged anyone with information to contact the Shah Alam police headquarters or investigating officer Anuar Amilah at 019-2255597.

Islamic development department (Jakim) director-general Sirajuddin Suhaimee yesterday said Jakim will investigate the programme as it was linked to acts of idolatry (syirik) and immoral rituals.

Selangor menteri besar Amirudin Shari said today that while the event had no connection with the state government, he was concerned about the allegations.

“We need to conduct a comprehensive investigation and take strict action against anyone involved,” he said in a Berita Harian report.

The motivational event, aimed at a Malay audience, involved about 50 female participants and was held at Shah Alam from Sept 27 to 30 last year. It gained public attention after a Facebook user claimed that troubling events occurred on the final day.

According to the netizen, the session took a disturbing turn when a female speaker entered wearing a bikini, proceeded to strip naked and began dancing with members of her group.

They then allegedly encouraged participants to follow suit, removing their clothes after being given a mysterious drink.

The participants were also reportedly instructed to take part in rituals described as a “sacred bath” and “rebirth”.
