In three five-minute segments aired over three days in March, 10 women taking part in men's magazine FHM's Girl Next Door competition were asked to whip off their bras in the shortest time, without exposing themselves.

The segments, called No Bra Days With The Muttons, were part of the station's morning show, hosted by DJs Justin Ang, 25, and Vernon Keith Anthonisz, or Vernon A, 34, for the past two years.

Video clips of the women removing their bras were posted on MediaCorp Radio's podcast website, and subsequently made their way onto video-sharing website YouTube.

At least one member of the public complained to the MDA. After investigations, it found the radio station in breach of the Radio Programme Code.

The code states that 'broadcasters must exercise sensitivity and avoid humour which offends against good taste and decency'.

A MediaCorp Radio spokesman said yesterday: 'We accept MDA's decision and recognise that the segments could be seen as being controversial. We sincerely apologise to those offended by the segment.'

She added that the DJs have been asked to be more mindful in the future. No other action will be taken against them.

This is not the first time the code has been flouted.

In 2004, the same radio station, then known as Perfect 10, was fined $30,000 for carrying sexually suggestive segments on its morning show, Morning Madness.

The co-host, then part-time DJ Sheikh Haikel, was dismissed, while partner Daniel Ong was suspended from on-air duties for a week.

In 2003, UnionWorks was fined $15,000 for featuring explicit sex discussions over the air on WKRZ 91.3FM's morning show. The DJ, Pete Leung, was sacked subsequently.
