The stabbing on a busy south London street this afternoon is believed to be related to Islamic terrorism.
Three people were injured in the attack on Streatham High Road, Lambeth at about 2pm on Sunday.
Two were stabbed by a knifeman while a third received minor injuries from glass after a firearm was discharged. All three victims have been taken to south London hospitals, and one man's injuries are being treated as threatening.
A male suspect was shot by police officers and died at the scene.
Deputy Assistant Commissioner Lucy D'Orsi from the Metropolitan Police says a device was found trapped to the suspect's body, to which specialist officers attended.
The device was quickly found to be a hoax explosive vest.
"The situation has been contained and officers from the Met’s Counter Terrorism Command are now leading an investigation into the incident," Comm D'Orsi said.
"The incident was quickly declared as a terrorist incident and we believe it to be Islamist-related."
SKY News reports the suspect was released from prison in January.
Officers are continuing to work in the area and Streatham High Road remains closed to the public.
"We would like to thank the numerous members of the public who assisted officers and ambulance staff this afternoon following a very confusing and alarming incident," Comm D'Orsi said.
"Public safety is obviously our top priority and to reassure the public we will be enhancing police patrols in the area."
Anyone with information, images or footage of the incident is asked to share them via the UK Police Image appeal website at www.ukpoliceimageappeal.com.

"I would also like to reiterate our earlier pleas for common sense and restraint in circulating pictures and videos of this incident – including images of the officers involved and of the victims," Comm D'Orsi said.
"I would also ask the public to continue to remain vigilant and report any concerns they have to police."
