A man has plunged to his death after "planking" on a seventh-storey balcony in Brisbane's inner-south this morning

A man has plunged to his death after "planking" on a seventh-storey balcony in Brisbane's inner-south this morning, police have confirmed.

Acton Beale, aged 20, fell from the balcony of a unit block on Main Street in Kangaroo Point shortly before 4.30am.

He was trying to lay face down on the balcony railing of his apartment when he suddenly fell.

Paramedics spent 20 minutes trying to revive Mr Beale at the scene, however, he died a short time later.

Planking, which involves somebody lying flat on their stomach in unusual or different environments, is a burgeoning internet craze that has attracted thousands of fans right across Australia.

Photographs of their exploits are usually shared through social media sites such as Facebook.

Deputy Police Commissioner Ross Barnett today said his worst fears about planking had been realised.

“This morning we have seen a young man take this activity a step further and attempt to plank on a balcony. Unfortunately he has tragically fallen to his death,” he said.

Mr Barnett said the 20-year-old and another person had been out during the night and had been planking in various spots on their way home.

"He has tragically lost his footing and fallen to the ground below," he said.

"It is what we've been fearing."

Mr Barnett warned people against taking unnecessary risks in a bid to out-do each other for the ultimate photograph.

“Accepting a risk of injury for yourself is one thing, but the potential is there for others to be injured as a result of your behaviour,’’ he said.

Earlier this week, a man was charged in Gladstone for trespassing on police property when he "planked" across the back of a police car.

"If other people break the law during this activity they will be charged as well," Mr Barnett said.

“But no penalty will ever return this young man to his family and friends.

‘‘This is a tragedy and our condolences go to the family.”

People have already condemned the internet craze on Facebook following the man’s death.

‘‘One life has been lost because of this! Think of what could happen if it went wrong. Don't be stupid ... think before you do this!’’ one person wrote.

Investigations are continuing.

Citibank (C.N) said a former employee had committed fraud in Indonesia and sought to reassure card clients on Saturday, a day after the central bank slapped lengthy bans on its credit card and wealth management businesses.

Citibank (C.N) said a former employee had committed fraud in Indonesia and sought to reassure card clients on Saturday, a day after the central bank slapped lengthy bans on its credit card and wealth management businesses.

The sanctions came as Indonesian police investigate both the death of a Citi credit card client following questioning by debt collectors and a case of alleged embezzlement of around $2 million in its wealth management business.

Citi, which has previously only said it uncovered suspicious transactions, sent a letter to credit card holders on Saturday aimed at keeping them onboard, saying it had taken corrective action and the suspensions would not impact clients.

"We regret the two recent incidents involving the tragic passing of a credit card customer and the unacceptable fraudulent actions of a former employee," said Citi country officer Shariq Mukhtar in the letter.

"We are committed to restoring public trust in our franchise."

Police have detained a former wealth manager at the U.S. bank and said the case involves around $2 million.

An Indonesian woman has filed a civil suit against Citi seeking $347 million in damages, after her husband died on March 29 following questioning over bills on a Citi credit card.

Indonesia's central bank barred Citigroup's local unit from adding new credit card clients for two years and new customers for its premium wealth service for a year starting May 6. It said if the police found crimes were committed, it would revoke the bank's operating license.

The penalties will hit the expansion of Citi's business in Southeast Asia's biggest economy, where global banks are seeking to tap rising middle class wealth and millionaire tycoons.
