British citizen refused help over kidnapped son by British Embassy?

Amazing what you see on Twitter. A British citizen called Martin Perry, who lives in Thailand, has apparently had his son kidnapped by his wife's family, and the child, who is a British citizen, is being held to ransom.

About 7 hours ago he posted,

A very serious request: Does anyone have any contacts or friends in the Police here in Bangkok who might be able to help us? Son kidnapped

He later posted saying,

I went to the British embassy already, they said they cannot help

It also seems he's been receiving threats of violence since the child was taken.

Funny old world.
