London-wide assembly member Murad Qureshi, and Dr Onkar Sahota AM for Hillingdon, called to get more weapons off the streets, after 15 teenagers were stabbed to death last year in London.
The latest Metropolitan Police figures for knife crime with injury with victims under 25, among west London boroughs, showed Hounslow as recording one of the highest jumps with 47 incidents, or a 52% increase in the last 12 months to November 2015.
However Harrow recorded a 36% fall, from 33 incidents in the 12 months to Nov 2014 down to 21 in 2015.
Across London figures for knife crime rose by 8% to 3,665 incidents in the year to November 2015, but worryingly, nearly half of these incidents involved young people.
London-wide London Assembly Member, Murad Qureshi AM, said: “With both the Mayor and Commissioner now agreeing to look at our proposals for a knife amnesty, we’re one step closer to getting more of these weapons off the streets where they can do so much damage.
“After the recent increase in the number of young people stabbed to death in the capital the last thing anybody wants to see is another life lost and another family devastated by these horrendous acts.
Dr Sahota added it is important the Mayor “recognises the positive impact allowing people to hand over their knives without fear of prosecution could have.”
Metropolitan Police Commissioner Sir Bernard Hogan-Howe and the Mayor of LondonBoris Johnson are reported to be considering the move, according to the London Assembly.
During Mayor’s Question Time on December 16 Mr Johnson responded to calls for a knife amnesty saying “I think that the amnesty proposal is something that should be considered.”
He said he would consult with the Commissioner, about the proposal.
When asked about the possibility of an amnesty at a London Assembly Police and Crime Committee meeting on December 17, Mr Hogan-Howe said “we’re having a look at how we might do this.”
