Police have launched a probe after reports two planes flew under a landmark Highland bridge

Officers say the possible 'unofficial aeronautical acrobatics' which took place on Tuesday afternoon at the Kessock Bridge in Inverness have been reported to aviation regulators.

They say it is thought three planes were seen flying past the main bridge linking the A9 from the Highland Capital over the Moray Firth to the Black Isle.

Two of the aircraft were believed to have flown beneath the huge bridge before meeting up with a third plane and continuing onwards.

Nobody is believed to have been hurt, but the incident is thought to have been witnessed by dozens of shocked motorists and people on the ground.

There is no further description of the type of planes involved.
