Jordan Johnson-Doyle’s mother, Leanne Burnett, said the family is worried as they have yet to receive any news of his whereabouts.

She said her husband is in Kuala Lumpur and has been meeting with the police to gather information.

“We are distraught and pray that he is well somewhere. The family is seeking the help of anyone who saw him at his last-known location to come forward and inform the police.

“My other son and I are leaving for Malaysia later today. We will do all we can to locate our son,” she told FMT in a phone interview.

It was earlier reported that Johnson-Doyle was on a solo backpacking tour of Southeast Asia.

He is believed to have gone to Healy Mac’s Irish Bar in Bangsar, Kuala Lumpur, for a pub quiz, based on a photo he sent to his mother.

Burnett told The Daily Mail UK that even if her son’s phone or laptop had been stolen, Johnson-Doyle knows her number and would have found a way to call.

She said the Find My iPhone app showed his phone last pinged near a residential building close to the bar, with the signal going silent three days later on May 30, possibly due to a dead battery.

A spokesman for the British high commission said they are “supporting the family of a British man reported missing in Malaysia”.
