Members of the Sawad special police task force entered the premises after the shooting and arrested a Chinese man.

Pol Capt Phanthep sustained three gunshot wounds – to his shoulder, chest and stomach.
He was admitted to Chon Buri Hospital in a serious condition.
Pol Snr Sgt Maj Kreetha was shot in the right leg and admitted to Bangkok Pattaya Hospital.
The two officers were working with the Provincial Police Region 2’s transational crime suppression team.
Natthawut Donchaisong, 41, a gardener, told police he was cutting grass in front of the house when police arrived in 3-4 cars, got out of the vehicles and approached the house.
He heard the sound of knocking on the glass door twice, followed by gunshots.
He heard at least 10 shots as he quickly ran into hiding in front of the house.
A member of the team involved in the raid said they were armed with a search warrant and went to the house to execute it.

A combined team of Chon Buri, tourist and immigration police inspects the scene on Wednesday evening, led by Pol Lt Gen Thiti Saengsawang, acting chief of Chon Buri police.
A police source said a 9mm machine pistol was used in the shooting. Officers found more than 40 spent 9mm cartridges scattered inside the house, near the door.
Thai media reported that the two injured officers were among seven police, armed with a search warrant from the Pattaya Provincial court, who went to the house.
They were looking for evidence that a group of Chinese nationals who rented the house might be members of a mafia gang, as they seemed to be unusually rich.
