Five 14-year-old girls were racially abused and attacked by older teenagers on a bus.
The girls were on the 83 bus in Wembley when the older teens racially targeted the other girls on December 29, 2023.
The Metropolitan Police says that the girls were abused and assaulted at around 6.20pm, but none were seriously injured.
It was reported later that evening and an investigation was launched.
After carrying out a number of enquiries, photos have been released of two people officers would like to speak to.
PC Matt Cannon, who is leading the investigation, said: "Thankfully incidents of this nature are incredibly rare on the bus network, however we will not tolerate hate crime and we are working to identify these people as soon as possible."
Anyone who recognises the people in the images is asked to call 101 quoting CAD 5443/29Dec. Alternatively contact Crimestoppers anonymously on 0800 555 111.
