Sixteen sheep were killed on Wednesday evening when cars ploughed into a herd that wandered onto the motorway near Pissouri, police said.
Police received a call at around 7.30pm that a flock of sheep belonging to a 52-year-old farmer had wandered onto the highway near the Pissouri exit causing a collision involving three cars.
A small stretch of highway near the Pissouri exit was closed for more than an hour while clean-up crews cleared the road.
The 52-year-old, whose farm is close to the highway, told police that a gate had accidentally opened and the sheep had wandered off.
He was held by the police for questioning but later released.
