Palestinian flags which were attached to lampposts in Tower Hamlets are being removed after concerns were raised with the police.
Concerns were raised after videos on social media showed several lampposts had been attached with Palestinian flags on Bow Road, Bethnal Green and Brick Lane.
While the Met Police said no offence had been committed, it had raised the issue with Transport for London (TfL) who is responsible for the roads, and Tower Hamlets on Monday.
Scotland Yard said in a statement: "There are some situations where the presence of a flag or banner or the use of specific words or phrases could be seen as intimidation.
"In some circumstances, it could also be seen as intending to cause harassment, alarm or distress."
Both Tower Hamlets and TfL have said they are in the process of removing the flags while a Labour councillor from another east London borough, who asked not to be named said they were concerned to see so many flags on one street.
"If I was from certain communities I might not feel safe," the councillor said.
TfL said in a statement: "We are investigating reports of unauthorised flags on the road network in Tower Hamlets and are removing these swiftly where they are found to be attached to TfL infrastructure."
A spokesperson for the council added: "A number of Palestinian flags have been put up by the public in recent weeks.
"While we appreciate people want to express their support for Palestine, we have a routine responsibility to monitor and maintain council infrastructure.
"As a result, the situation is under daily review."
This comes after TfL suspended a Tube driver who appeared to lead a ‘free, free Palestine’ chant on a Central line train.
Footage posted online apparently showed the chant being led over the train’s speaker system on Saturday, as about 100,000 protesters took part in a pro-Palestinian demonstration.
The words "free, free" could be heard and passengers responded "Palestine" - a popular chant at protests.
The mayor said it was “the right thing for TfL to have done” and that the organisation now needed to follow its processes on whether the driver should face disciplinary action.
