A Canadian chef who was arrested in May this year is being investigated by the UK's National Crime Agency over the deaths of 88 people in the UK. 

The NCA revealed in April that a large number of people in the UK purchased suicide kits from Canada-based websites, which are reported to have been run by Law.

Kenneth Law, 57, is a Canadian chef working at a high-end hotel and a former aerospace engineer. He was charged in May with two counts of aiding suicide after admitting to an undercover reporter that many of his customers had died. 

According to The Times, in the initial stages of the investigation, Interpol transmitted a list containing the details of 232 British customers who purchased the kits.

Later reports suggested that among those who purchased the kits, 88 customers in the UK died. 

Law is charged with selling over 1,200 lethal kits to suicidal people across 40 countries, and if charged with the deaths of the 88 people, he will have to be extradited to the UK.

"Our deepest sympathies are with the loved ones of those who have died. They are being supported by specially trained officers from police forces," Craig Turner, an NCA deputy director, said.

"In consultation with the Crown Prosecution Service, the NCA has taken the decision to conduct an investigation into potential criminal offences committed in the UK. This operation is under way."

Canada is currently working on an investigation, but authorities said they do not take cases from outside their jurisdiction.
