The man in the DVDs is said to resemble a senior MCA politician from Johor.

Police have started an investigation into the distribution of the DVDs in several places, including Muar and Batu Pahat.

Johor police chief Datuk Hussin Ismail said police were investigating the matter under Section 292 of the Penal Code for distribution of obscene materials.

The discs were reportedly dropped into the postboxes of selected houses and shops in Muar and Batu Pahat. Residents found the discs on Sunday morning.

The name of the minister involved is said to have been written on the DVD cover.

"We have reason to suspect that the discs contain pornographic material and, as such, it is an offence to either possess or distribute them," Hussin said.

Those found guilty under Section 292 may face a jail term of up to three years, a fine or both.

"I urge those who have received the discs to come forward and inform the police."

A New Straits Times reader who had watched the two DVDs called to describe the video recording.

According to him, the movements, build and complexion of the man in the DVDs resembled that of a prominent Johor politician.

The first disc, which is 60 minutes long, consists of four different angles of a single black and white recording of what appears to be a hotel room.

The second disc is an enlargement of the high angle above the bed. It is not known who made the recordings.

The reader claimed he found the DVDs in his letterbox on Sunday morning.

Chinese newspaper Kwong Wah Yit Poh reported yesterday that its Seremban office received a copy of the DVD in an envelope. There was no stamp on the envelope.

Meanwhile, MCA president Datuk Seri Ong Ka Ting yesterday declined to comment on the matter.

Attempts to contact other senior MCA leaders also drew a blank. Calls to MCA secretary-general Datuk Ong Ka Chuan, Health Minister Datuk Seri Dr Chua Soi Lek and Human Resources Minister Datuk Seri Dr Fong Chan Onn went unanswered.

A political aide to an MCA central committee member said: "For now, it still seems confined to rumours."

An aide to another party leader said: "Maybe after today, (the central committee members) will have a clearer picture of the situation."

Johor Barisan Nasional chief Datuk Abdul Ghani Othman, repeatedly said: "I don't know, I don't know. Really? Is that right? I don't know how to respond."

Johor MCA liaison deputy chairman Tan Kok Hong said: "I do not know anything."

Former MCA vice-president Datuk Chua Jui Meng said: "I don't know about any of this".
