As Muswell Hill parents and local councillors held a public meeting looking at how to tackle rising knife crime in the area, two young men were arrested on suspicion of carrying a blade minutes away.
Police and community workers had also attended the June 10 public meeting held in response to perceptions of rising knife crime.
Organiser Cori Josias said: "I was sitting at home and saw news about the [April 29] stabbing near the Mossy Well.
"This was after one on the 134 bus, and I just wanted to know: what can we do?
"I didn't even know at the time my own son had been threatened with the prospect of a knife. I'm aware Muswell Hill isn't the worst affected, but it is where I live."
At the meeting, which saw the community search for practical solutions to rising crime, Haringey's community safety lead Cllr Mark Blake (Lab, Woodside) said: "It's very easy for us to draw up bridges. I think it's important that we are building bridges across Haringey."
Cllr Blake, who represented Muswell Hill until 2018, emphasised the council was working behind the scenes to improve CCTV coverage and work with schools.
He also said he would like to see drug decriminalisation, referencing the Mossy Well stabbing as an example of the impact of a failing approach to drug enforcement.
The co-heads of Fortismere School were unable to attend, but sent a message to be read out. They said: "It is very much at the forefront of our curriculum that we are teaching our students to be safe, too."
Muswell Hill councillor Julia Ogiehor also spoke. She said: "When I became a councillor this was one of the main issues I wanted to take up. I want to reiterate there are things happening behind the scenes."
The same night, two young men, 16 and 21, were arrested on suspicion of possession of an offensive weapon - a lock knife - and drugs.
Sgt Leon Christodoulo told the meeting it was "essential" that muggings and other crimes were reported so as to improve police intelligence.
A police spoksperson said they were aware of the upturn in incidents and working with neighbours to combat it.
They said route-planning, looking confident and hiding valuables could help prevent people becoming victims of crime.
