Detectives are hunting three men who stole cash and a mobile phone from a teenager after threatening him with a metal pole.

A 17-year-old man was walking along the B3016 in Hook towards Hartley Wintney when a black Ford Fiesta pulled up behind him at about 11pm on November 16.

Three men got out of the car and one of them threatened the teenager with a metal pole and demanded his wallet and phone.

He handed over the items and the men got back into the car and drove off towards Odiham.

Police have issued an e-fit of one of the men.

He was white, 5ft 9ins tall, of skinny build, about 17 and wore a black hooded top with the hood up and a cap underneath the hood, grey tracksuit trousers and white trainers.

Another man was white, 5ft 9ins tall, around 17 years old and of skinny build.

He was wearing a red hooded top with the hood up and a black cap underneath the hood, black or navy blue jeans and white shoes.

The third man was white, 6ft 4ins tall, skinny and around 17.

He wore a black hooded jacket with the hood up and a black cap underneath and four gold sovereign rings on each finger of his right hand.

Det Con Mark Ogburn of Aldershot CID said: "Although this incident happened late at night someone may have driven past and witnessed it.

"We are keen to trace the men responsible for this attack and would urge anyone with information or anyone who recognises the man in the image to contact police as soon as possible."

Anyone with information should contact Det Con Ogburn at Aldershot police station on 0845 0454545 or call Crimestoppers anonymously on 0800 555111.

The attack has led to police offering a number of safety tips.

They are urging people to look like they know where they are going.

People wandering around with a map and looking confused are more likely to be targeted, they warn.

Try to keep valuables, such as laptop computers, jewellery or mobile phones out of sight and if someone tries to take something from you, it might be better to let them take it, rather than risk being injured in a confrontation.

If you decide to defend yourself, remember that your attacker might be stronger than you so it is often better just to shout loudly and run away.

When out walking or jogging, do not listen to a personal stereo as you might not be able to hear someone approaching.
