Two days after Arwuth Worathavornwiwat's Mitsubishi pickup truck was damaged by a brick dropped from a bridge, police are still searching for the cuplrit, believed to be a motorcyclist.
Police from the Metropolitan Police Bureau's Division 8 and Samre station have checked the pictures from surveillance cameras in the area around the Taksin bridge on both sides of the Chao Phraya River and talked to local people, but they have made little progress finding the culprit.

Pol Maj Gen Ratsathakorn Yingyong, the division chief, ruled out personal conflict between Mr Arwuth and other drivers as a motive and said they were now focused on the wilfulness of the brick thrower.
The vandal dropped a two kilogram brick on Mr Arwuth's pickup truck, but he is not the only recent victim of flying bricks and rocks in Bangkok.
According to FM91 traffic radio station, run by the police office, seven attacks have been reported since early February this year. The other targets were two taxis, two private sedans and two other pickup trucks.
Only Mr Arwuth was attacked on the Thon Buri side, the other incidents were on the Bangkok city side of the river.
The vandal, or vandals, also struck on Vibhavadi-Rangsit road, in the Phaya Thai area, Pracha Songkroh road, Sala Daeng and Klong Ton.
Rocks were thrown from bridges in three cases and from the roadside or thrown by drivers, the radio station said. Two cases clearly involved motorcycle riders, but the other attackers could not be pinpointed.
Mr Arwuth was driving along Charoen Nakhon road, under the bridge. The investigation found that the brick was thrown from the inbound lane of the bridge.
Samai Supsaithong, a taxi motorcyclist working under the bridge, said he saw two bricks dropped from above, one hit the road and another slammed onto the roof of the vehicle.
"I've never seen anything like this before in the 10 years I have been driving a taxi motorcycle and picking up passengers here,'' he said.
