A police chief has warned people to lock up their bikes after a surge in thefts.

More than 50 cycles have been stolen from the streets of Hove since January.

Thieves simply cut through flimsy padlocks and chains securing them to railings.

In a number of cases they have got into communal hallways to take bikes from flats and other buildings.

Chief Inspector Marion Sandwell, police commander for Hove and Portslade, said: "There has been a definite increase.

"The number of pedal cycle thefts in Hove has risen since the start of the year.

"It is not a huge increase but we want to nip it in the bud before it does become a problem."

She urged bike owners to ensure their machines are properly secured when left.

Using heavy duty locks makes it harder for thieves to cut through them quickly.

Cycles can also be security marked to make them easier to identify when they are recovered.

Ch Insp Sandwell said: "We want to encourage more people to use pedal cyles to get around Brighton and Hove.

"Doing so helps us and our partners on the city council to reduce traffic congestion.

"I use my own cycle all the time and spent £60 on a substantial lock to secure it.

"It is heavy and can be a pain to carry around but it would take a thief seven minutes to cut through it.

"That acts as a deterrent to somebody who does not want to be noticed.

"some people have quite valuable cycles so it would make sense to spend a little more on securing them properly."
