PC Louis Blackburne-Maze, who is leading the investigation for the Met Police, said: “Everyone has the right to protest and to have their voice heard, but when that crosses the line into criminality, as it clearly did in this incident, we will take action.
“Elected representatives have an important role to play and they expect to be held to account, but that should not involve feeling unsafe. Neither they nor their staff should have to face targeted attacks and intimidation.
“Officers investigating this incident have examined CCTV footage from the local area and we have identified three suspects that we would like to speak to. I would urge anyone reading this appeal who recognises them to get in touch.”
At the time, the Met described the graffiti as “racially motivated”, adding that there is “no place for hate in London and it’s important that everyone feels safe on our streets”.
Although not all of the slogans are visible, the graffiti appears to say “No genocide in our name” and “Free Palestine”.
