The Disease Control Department has asked the Bangkok Metropolitan Administration to take legal action against people involved with the birthday party of actor Techin Ploypetch, also known as DJ Matoom.

Techin is in hospital being treated for the coronavirus disease, with some Thai media reports making reference to a "superspreader" and efforts to conceal his infection.

The Centre for Covid-19 Situation Administration updated the number of Covid-19 cases linked to the celebrity DJ's illegal party.

There were now 26 people confirmed infected with Covid-19 and 113 at-risk people.

Another 53 were considered at low-risk of infection, but the figures could rise.

The Disease Control Department told the BMA that people who concealed information violated several laws.

Legal action could target those in charge of the party for violating the ban on crowded gatherings to help control the disease, as well as partygoers.
