Mechanical equipment has been used to put up loyalist and other flags in east Belfast as the PSNI looked on.
A large number of union and other flags were put up along the Newtownards Road last Sunday by loyalists using telescopic equipment, which blocked part of the main arterial route.
Men in hi-vis vests could be seen putting up the flags and standing on the roadside below.
At one stage, a PSNI car passed along the road but officers are not thought to have intervened.
Earlier this year, the PSNI issued a new policy designed to clamp down on controversial public displays, including paramilitary flags and emblems.
In a statement, a spokeswoman for the PSNI said the force is aware that flags were put up in the area.
“The Police Service of Northern Ireland considers each incident on a case-by-case basis, and the individual circumstances will determine what specific action police take,” she said.
“Where any offences have been committed, the circumstances will always be investigated.
“The primary responsibility for removing flags from street furniture rests with the property owner and the Police Service of Northern Ireland will consider any requests for assistance.”
The spokeswoman added that PSNI officers “engage and work with local communities and partner agencies in relation to any complaints about flags”.
