Driver Thongsuk said his bus was heading to the Phra Pradaeng stop and most passengers were getting ready to get off when he lost control of the bus. 
He said the road was slippery and the wornout bus tyres could not grip properly. 
He said that as he lost control, he saw many vehicles on the right lane so he decided to stop the bus by crashing it into the tree instead of the other vehicles. 
Chitawan said police would interrogate the injured passengers before deciding whether to charge the bus driver.
