An 18ft pregnant Burmese python, which can crush its prey to death in a matter of seconds, is believed to be on the loose in Hove.

Neighbours have been asked to check their outhouses, garages and sheltered areas of their gardens in search of the missing snake named Marylin.

Some are terrified they could stumble upon the creature slithering in their flower beds.

Others have found the prospect of a snake in their neighbourhood amusing.

Scores of posters warning Marylin is missing have been put up in Leicester Villas, New Church Road, and Worcester Villas.

However, whoever put up the posters has not given their contact details.

The posters ask anyone who finds the snake curled up somewhere to phone the police.

The RSPCA has warned people not to touch or poke the reptile if they find it.

Pregnant pythons can get angry and tetchy very quickly and can attack anyone who threatens them.

They need constant care, especially when pregnant.

The posters show a darkened picture of the snake curled up in what appears to be shed.

Police said Marylin's owner had not told them the snake was missing but advised people to contact the RSPCA should they see it.

Officers are still unsure if the posters are a hoax but neighbours in the area are taking the warning seriously.

Joanna Mason, 80, of New Church Road, said: "A lot of people have seen the notices and are worried.

"If the snake is attacked by my Yorkshire Terrier out of curiosity, it could easily swallow her whole. It is quite frightening."

Tutor Mark Sage, of Leicester Villas, said: "I will check my sheds but I will not touch the snake if I see it."

Robin Johnson, who runs Rik's Record shop in Portland Road, Hove, said: "I shall look around in the mornings when I open up but I shall be surprised if she comes in here as there is a concrete floor and she will not find it comfortable."

Geoffrey Chapman, 80, of New Church Road, said: "I will probably not put the rubbish out at night in case the snake is around but I am not too worried.

"I have seen plenty of snakes while working in Africa and there are a lot of snakes in the business world."

A spokeswoman for Hove police said: "We don't know whether it is a hoax or not. "

A spokeswoman for the RSPCA said: "If anyone sees the snake, they should keep it contained.

"They should not approach it or try to pick it up. We have trained RSPCA inspectors who know how to deal with snakes."

People should phone the RSPCA on 08705 555999 if they see Marylin.
