Police this week revealed the results of a knife amnesty and repeated a promise that anyone caught carrying a blade would be arrested.

Speaking at an update on the amnesty, Croydon's Chief Superintendent Mark Gore said he was happy with the response from the public. But he also warned that police would take action against those found carrying knives.

He added: "It is fair to say that we were not expecting the knife amnesty bins to be overflowing with knives, but we have so far had more than 70 knives surrendered.

"The campaign set out to raise awareness of the real dangers of carrying knives and so far we have had a positive response.

"We still have another week to go, so it is still not too late to bin that knife. As I have said before, my message is clear, anyone caught in possession with a knife will be arrested."

The amnesty was launched last month by Anita Brown, whose teenage son Gavin was stabbed to death, and is due to end next week.
