A performance artist who released seven yellow balloons at an event attended by Prime Minister Najib Abdul Razak this afternoon has been questioned for insulting the premier.

Bilqis Hijjas was detained and questioned by police at the Dang Wangi district police headquarters, under Section 504 of the Penal Code for intentional insult with intent to provoke a breach of the peace or another offence.

Those found guilty can be jailed for up to two years or fined or both.

Najib ( photo ) was on the ground floor at the centre court of Pavilion mall to officiate the Diversecity Kuala Lumpur International Arts Festival when the balloons were dropped from a higher floor.

The seven Bersih-yellow balloons were decorated with the words "Free media", "Democracy" and "Justice", among others.

Najib, and his wife Rosmah Mansor, did not react to the incident.

Bilqis was subsequently detained, and handed over to the police.

She was later released after being questioned and her fingerprints taken.

Lawyer Michelle Yesudas who represented the 35 year old said the case was absurd.

"The case should speak for itself. After the exemplary behaviour of the police yesterday at Bersih, for Bilqis to be treated like a criminal is absurd," she told Malaysiakini .

Bilqis’ act comes a day after the Bersih 4 rally, which was attended by tens of thousands, ended in a clear show of no confidence for Najib.
