Leaders in the North East have warned a "small minority" of people who may be thinking of disrupting Newcastle's Platinum Jubilee celebrations.
Leaders from councils in Newcastle, Gateshead, Durham, North Tyneside, South Tyneside, Northumberland and Sunderland have come together to encourage locals to stay safe during the celebrations over the long weekend.
A joint statement read: "Our cities, towns, and villages are keen to celebrate this historic moment, and we want everyone to enjoy the extended bank holiday.
"We know that whenever big celebrations come around, the overwhelming majority of people are considerate of others around them.
"However, a small minority can have a big impact and potentially prevent others from enjoying themselves during a once-in-a-lifetime event such as this.
"Please be mindful of others in whatever it is you’re doing, whether it’s while using the public transport network to travel to and from an event in the region or making sure your local community’s street party passes without incident.
"Our Emergency Services will be working closely with communities to keep us all safe, and it is important that they are not placed under any more pressure. If you do see or hear of any anti-social behaviour or criminal activity, please report it."

Cllr Amanda Hopgood, Leader, Durham County Council
Cllr Martin Gannon, Leader, Gateshead Council
Cllr Nick Kemp, Leader, Newcastle City Council
Norma Redfearn CBE, Elected Mayor, North Tyneside Council
Cllr Glen Sanderson, Leader, Northumberland County Council
