A six-year-old boy handcuffed a police constable and sprayed a superintendent with training pepper spray before speeding off in a police car.

Little Malachi Tyler spent the afternoon calling the shots at Kingston police station today as part of a bucket list of activities he would like to do in his lifetime.

Malachi, the youngest of seven siblings, was diagnosed with an incurable brain tumour and neurofibrosis when he was just 15 months old and has endured months of chemotherapy and four surgeries this year alone.

But mother Emma, 41, said her son - who lost his eyesight just before his second birthday - was just a “normal happy little boy”.

She said: “When he gets poorly we have to call 999 a lot and go in the ambulance – but he isn’t scared. He is always excited.

“We love him loads. We have treated him like a normal child. He gets told off like a normal child – that’s what makes him who he is.

“He loves music – Katy Perry, The Script. He is learning to play the piano at the moment. He is taking lessons from a blind pianist. It is quite funny to see them together. He is very sociable.

“He says purple is his favourite colour but he can’t see.”

Malachi's bucket list also includes a trip to Disneyland and Lapland.

He has already fed his favourite animal, a giraffe, and will be a mascot at a football match this weekend.

But he had always dreamed of arresting someone and going into a police cell.

As he was led into Kingston’s new custody suite, he asked: “Are there any naughty people inside?”

Police Constable Coral Kean replied: “No, they’ve all been locked away for you.”

Mrs Tyler, from Tunbridge Wells in Kent, said: “He wants to be a police officer when he is older.

"He is quite a bright little lad. He has always wanted to do these things and we thought it’s good because it is something to look forward to.

“He is very popular. He will take all this in and tell everybody about it. It is quite heartwarming. It’s amazing that they have done this for him.”

Chief Inspector Gary Taylor, from Kingston police, said: “It’s been great to have Malachi. We have given him full access to anything in the police station – he will probably arrest me and put me in a cell later.”

The visit was organised by police constable Alex King who met Mrs Tyler while he volunteered with the Emily Ash Trust charity.

Malachi got the chance to show off his Braille reading skills at the station and was given a certificate for his day's work.

He will have another scan later this month to find out if his tumour has continued to grow and whether he will need more treatment.

Mrs Tyler said: “He asks a lot of questions. He said to his sister ‘I wonder what it’s like to see’. It is upsetting but I have to be positive. We are so proud of him.”
