UPDATE: Teen found after mum's heartbreaking plea

Kieran Cheltenham, 18, hadn't been seen since 10am yesterday, when he was spotted walking through Fleetwood with an undentified man.

He was found by police in Fleetwood at dinnertime today and arrested on suspicion of arson.

Describing her son as '˜vulnerable', Donna Cheltenham, 35, of St Annes, said: 'On Monday night, I got a message off his friend saying, '˜ring this number' because he had been spiked and his phone had been stolen.

'He was out of it and I called the police.'

Kieran, who worked at The Beach Cafe in St Annes until last week, will now be questioned by detectives about a fire at a block of flats in Queen Street, Blackpool, which happened at around 9.05pm on Monday.

A spokeswoman for Lancashire Police confirmed officers were looking for Kieran and wanted to speak to him about the blaze, which is being treated as arson.

Two people had to be rescued by firefighters after a sofa was set alight inside a ground floor flat, police said earlier this week.

Others managed to get out before crews from Blackpool, Bispham, and South Shore fire stations arrived, the fire service added

UPDATE: Kieran Cheltenham was charged in connection with the incident but a not guilty verdict was returned by the jury at Preston Crown Court on February 5, 2018 after the prosecution offered no evidence.
