A driver tried to ram his car early Tuesday into the residence of Taiwanese PresidentMa Ying-jeou in the second such incident in a year.
Chen Ping-sung attempted to ram a door of Ma`s guarded residence in central Taipei, police said.
But the sedan`s tyres were punctured by metal spikes installed on the ground as a security measure and the door was undamaged, they said.
Chen had attached a bucket of red paint to his front bumper which spilt onto the car.
He was arrested on the spot by security men and taken to a nearby police station for questioning.
Ma was jogging in the residential compound at the time, said his spokeswoman Ma Wei-kuo.
The suspect told police he was trying to protest at negligence by the government bureaucracy which had caused many medical disputes.
In January a man, angry at a court ruling in a case involving his divorced wife, rammed a 35-ton truck through a bulletproof screen and into the main gate of the presidential office.
