A senior police officer has been infected with the coronavirus, and it could be linked to the birthday party held by Techin "DJ Matoom" Ploypetch.
His infection prompted the closure on Monday of the Criminal Records Division at police headquarters, where the officer works, for three days. It will be sprayed with disinfectant.
Pol Maj Mongkol Juthanon announced that his test for the virus on Friday was positive and he was under treatment at Police General Hospital.
His timeline included a visit on Thursday to his condominium by a friend who had been at DJ Matoom's party.
The celebrity DJ, who works for GMM Grammy and is an actor, hosted his birthday party at the Banyan Tree Hotel in Bangkok on Jan 9. He was later found to be infected with the Covid-19 virus.
He earlier attended a New Year celebration in Chiang Mai from Jan 1-5.
The Disease Control Department has found 19 cases related to the two parties, so far.
Department director-general Opas Karnkawinpong said on Sunday the virus was probably carried to Bangkok by a man who attended the Chiang Mai event. He was also at DJ Matoom's birthday party.
It was still unclear whether DJ Matoom attended the New Year party every day, or just on some days.
But the visitor to Pol Maj Mongkol's residence on Thursday was first tested a week earlier, on Jan 16, and it returned negative.
Dr Opas renewed his warning that people should avoid congested places, especially where there was poor ventilation.
Pol Maj Mongkol is the son of former deputy police chief Pol Gen Chongrak Chuthanon.
