Attempts are still ongoing to round up all the cattle in a herd of 120 which caused roads chaos in a breakout north of Forfar.
Several vehicles were damaged and at least one of the animals was killed as the beasts stampeded from a field at Drumclune just after 7pm on Thursday night.
The Forfar to Kirriiemuir road via Horniecross remains closed and police have also blocked the southbound approach to Forfar from the A90 at Quilkoe as efforts continued to capture all of the escapees.
They are understood to have broken through a secured gate at the field a few miles north of Forfar, but the cause of the animals fleeing is not known.
The herd then ran south via Horniecross towards Forfar, with numerous motorists encountering them en route.
A Volvo and a Vauxhall Vectra which were badly damaged after being struck by the cattle, but the drivers of the vehicles escaped unhurt. At least one cow is known to have died during the incident.
The majority of the animals were black, thought to be Limousin bullocks, making it difficult for drivers to spot them in the darkness of the unlit back road.
Around 30 cattle made it to Forfar, where further chaos was avoided after they were diverted right at the Zoar Bridge onto Kirriemuir Road and then herded into a field entrance at Turfbeg Farm, between the town and the A90 Forfar bypass.
Others made it on to the Forfar golf driving range and were rounded up there.
A Police Scotland statement said: “Police Scotland is advising motorists on the A90 and surrounding rural roads to drive with caution in the area between Kirriemuir and Forfar after around 120 cattle escaped from a farm near Kirriemuir at about 7.15pm last night.
“Around half of the cattle were rounded up overnight, with the assistance of local farmers, however there are a significant number still unaccounted for and efforts continue today to corral them safely back home.
“Motorists should leave plenty time for their journey and are asked to remain alert and aware when travelling in this area of Angus.”
