They said they had not received any formal complaints.

British home appliance maker Dyson had told Reuters earlier that it was ending its contract with ATA after an audit of the company’s labour practices and allegations by a whistleblower.

Dhan Kumar Limbu, a former ATA worker, told Reuters on Thursday that ATA officials took him to a police station in June.

He said he was questioned about sharing information about conditions at the factory with activists and then beaten by police.

Police in Johor, where ATA’s factory is located, said they had not received any reports on the matter.

“Johor police take note of the issue that was reported and will conduct an investigation if what was reported is true,” the police said in a statement on Facebook.

ATA said on Friday it had appointed consultants to review findings of forced labour in an audit summary it received from Dyson and claims of physical abuse raised by a former worker.

The manufacturer said it had hired a law firm in Malaysia to conduct an independent review of the allegations of physical abuse by the former worker and a detailed report would be finalised soon.

Recently, human resources minister M Saravanan was reported to have said that the ministry would investigate Dyson’s decision to sever ties with ATA IMS.

In interviews with Reuters, seven current and former ATA employees said they had worked overtime in excess of limits under Malaysian law.

They also said they had paid recruitment fees in their home countries to labour brokers, a practice activists have criticised as a form of debt bondage.

Dyson contributes around 80% of ATA’s revenue.

Shares in ATA, which makes parts for Dyson’s vacuum cleaners and air purifiers, have plunged 55% since the Reuters report.
