According to the team that runs Alver Valley country park in Gosport, part of their herd of sheep was attacked by teenagers, who threw rocks and other objects at them.
The attack has left the sheep limping and bruised – with one even missing a horn.
Posting on social media, a spokesman for Alver Valley said: ‘Unfortunately a small fraction of our younger generation feel that this is acceptable behaviour – part of our herd were rounded up and cornered before having rocks and other heavy items thrown at them.
‘The three male teenagers were wearing a dark hoodie and two with lighter sweaters. All were wearing tracksuit bottoms.’
A police spokesman said: ‘ We were called at 3.33pm on Tuesday following a report of sheep being injured at Alver Valley Nature Reserve in Gosport at around 1pm on the same afternoon.
‘Three teenagers were seen in the area at the time.
‘The Neighbourhood Policing Team is actively undertaking enquiries in the area and speaking to people who may have seen what happened.’
