One police officer was hurt while trying to make an arrest at the Notting Hill Carnival – and a second was injured while going to his aid.
A male PC, 33, was taken to hospital after being attacked while trying to arrest a suspected drug dealer during the event in West London.
He was found in Lancaster Road at the junction with St Luke’s Road at around 3.15pm on Sunday with injuries to the head and torso.
The officer has since been discharged from hospital.
Colleagues also came under attack when they went to help him, and a 35-year-old female officer suffered injuries to her torso. She was taken to hospital but also released on Sunday.
Meanwhile, the Metropolitan police activated special stop and search powers across the Carnival between 7pm on Monday and 2am on Tuesday following a spate of violent incidents.
It was decided to impose Section 60 and Section 60AA orders in the area.
Section 60 of the Criminal Justice and Public Order Act 1994 allows senior police officers to authorise constables to stop and search people in a specific area, either where a serious public order problem is likely to arise or has taken place, or for offensive weapons or dangerous instruments.
Officers can conduct searches under the powers whether or not they suspect the subject to have been involved in wrongdoing.
Section 60AA gives police powers to order the removal of disguises where section 60 has been invoked.
The decision was taken “in response to incidents of violence, and intelligence received, which have taken place within a short period of time in the last few hours”.
Six men have been arrested on suspicion of attempted murder after a man suffered “a serious stab wound”.
In another incident shortly before 4pm on Monday several men were injured – one 29-year-old man sustained a serious stab wound and is in a stable condition.
Eight others also received knife wounds.
Eight people were arrested in connection with the disorder.
By 9pm on Monday there had been 123 arrests over the course of the day taking the total for the two-day event to 227.
