Police are hunting mindless thugs who used metal poles to smash a swans’ nest and eggs.
The makeshift weapons were repeatedly thrust into the large structure, close to a path in Solihull’s Tudor Grange Park.
The parent birds have not been seen since the attack.
Police have called on the public’s help in catching the culprits – and warned they could be banged up for six months.
The birds have endured a troubled time since making their home in the park. Pc Andy Timmins was contacted two months ago by users concerned about the birds’ safety because their nest was so close to a walkway.
He has worked with Solihull Council to create a metal barrier between the path and nest.
A police spokesman said: “While many welcomed the move and were eagerly anticipating the hatching of cygnets, others littered the nest and even threw sticks at it.
“The punishment for anyone found guilty of the theft of eggs or damage of a nest could be six months imprisonment and a hefty fine.”
Last week came sickening news the nest had been vandalised, sparking an angry response from locals on Facebook.
Gemma Workman posted: “I hope the culprits are found and punished. Why can’t people leave things alone?”
Rhona Myatt angrily said: “I get so angry when I hear of some moron destroying life and nature. What the hell is wrong with some people?”
Anyone with information can call Pc Timmins on 101 or via the independent charity Crimestoppers anonymously on 0800 555 111.
