The shocking double stabbing in two separate incidents in Hammersmith and Fulham has left a community in shock.
MP for Hammersmith Andy Slaughter has said while "such incidents are rare" he is "very concerned" following the two knife attacks.
"I am very concerned that two serious knife attacks have happened in a single day in busy parts of the borough", Mr Slaughter told getwestlondon .
"I will be in contact with the borough commander to find out how the search for the suspects is progressing and see how the victims are faring.
"Residents, especially children and the elderly, must feel safe to walk through our streets and parks."
The first attack on Thursday (January 5) saw a man in his 40s stabbed in broad daylight at around 1pm in Harwood Road at the junction with New King's Road in Fulham.
Police sealed off the area and the victim was taken as priority to a major trauma centre.
Later that evening, just before 8pm a boy aged 14 was found with a stab wound near a bus stop in Goldhawk Road.
Police believe the knife attack took place in Ravenscourt Park in Hammersmith and said the teen is fighting for his life in hospital.
The law has come under scrutiny as west Londoners were left angered by the events of yesterday.
Comments left on the Getwestlondon Facebook page included "the country has become weak with weak laws" and "what is happening."
Tala Sabi-aish commented: "Where is the proper law? "If they were scared to break it they wouldn't have even considered carrying knives, but its like a walk in the park....They truly don't care."
Helen Louise Sambaue added: "Why is the child out that late anyway. Hope he gets better."
