Police today warned people who are still keeping firearms despite a month-long amnesty: "We're coming to get you."

More than 1,000 weapons were handed in throughout Sussex during the campaign, which comes to an end today.

Officers leading the initiative say they are pleased with the result but fear it could just be the tip of the iceberg.

Today is the last chance for people to surrender them with impunity, as the amnesty runs out at midnight.

Assistant Chief Constable Geoff Williams said the campaign was just the start of a guns crackdown and officers would now be gathering intelligence on people still holding weapons and raiding homes.

He warned: "The message is hand them in while you can. Otherwise, we're coming to get you. The next stage is enforcement.

"In the wrong hands guns can frighten, maim or kill and every weapon handed in is one more that cannot be used in crime. Help us to make our communities safer."

A total of 156 guns were surrendered at Brighton police station in John Street alone during the month. A Magnum .357 was among the last to be given up.

Other weapons included a Kalashnikov assault rifle, a 1915 semi-automatic Becker and Hollander, crossbows, swords, pistols, shotguns, BB guns, air weapons and imitation guns.

One farmer handed over a mini-arsenal comprising a .22 pump-action rifle, a .22 rifle, two miniature snub pistols and hundreds of rounds of ammunition.

At Haywards Heath police station, one pensioner handed in a gun from the First World War.

A total of 64 weapons were handed in in the town, where one of the more unusual items was a harpoon gun, surrendered during the first week.

Officers at Crawley police station collected 144 firearms.

In East Sussex, police chiefs said they were delighted with the response from the public.

In Eastbourne, 95 firearms were handed over, in Hastings the tally was 99, Uckfield 49 and Bexhill 53.

Historic firearms will be sent to museums while others will be tested and some will be melted down.

So far, 235 firearms have been handed to police at Worthing and 109 in Chichester.

The amnesty ran ahead of new legislation which will make it an arrestable offence to possess a replica firearm or air weapon in a public place without reasonable excuse or lawful authority.
