A deflated French "Spiderman" Alain Robert said today he will keep his feet firmly on the ground and off Malaysia's tallest buildings after being arrested for trying to scale them.

Robert on Tuesday failed in his audacious assault on the iconic Petronas Twin Towers in Kuala Lumpur after authorities nabbed him while he was two-thirds of the way up one of the 88-storey buildings.

It was his second attempt in a decade to climb one of towers - once the world's tallest buildings - with just his bare hands.

"On Tuesday, I climbed it exactly on the same day 10 years ago," Robert told AFP .

"I have no reason to try again. I did it twice and reached 60 stories each time. Unless one day I can get approval and I can get to the top, there's no point," he added.

Robert was freed on bail on Wednesday by police, but his passport is being held while government lawyers decide whether to charge him for trespassing.

If found guilty, the 44-year-old rock climber could be fined RM2,000 or jailed for a year, or both. He was freed without charge after his first try in 1997.

Risky feat

Robert said his lawyers were working on a deal to keep him from prosecution. "If I sign something and promise not to do it again, I won't be charged ... which is a good deal. At the end of the day, it is better to have my freedom," he said.

The Frenchman also said he was disappointed at comments by fellow countryman, Christian Poncelet, the president of the French Senate, who had witnessed his attempt while on a visit to Malaysia.

Poncelet had criticised Robert's feat as risky and suggested he climb elsewhere instead of flouting Malaysia's laws.

"I was a bit surprised. I thought his reaction was very uncool and unfair," Robert said.

Down but not out, the French daredevil said he planned to climb more buildings in Europe, including towers in Frankfurt, Paris and Brussels, and would release a DVD of his feats.

"Climbing buildings is not illegal in some countries," he said.

Robert has been nicknamed "Spiderman" for his high-profile escapades, which include climbing the Eiffel Tower in Paris and the Golden Gate Bridge in San Francisco.
