Hibernian Football Club has launched an investigation after glass bottles were thrown onto the pitch during the Scottish Cup clash with Celtic at Easter Road.

On Saturday night, a bottle of Buckfast was thrown at Celtic star Scott Sinclair as he went to take a corner.

TV cameras showed referee Willie Collum handing it to a steward before play resumed at the Edinburgh stadium. Celtic went on to win the game 2-0.

A Hibs spokesperson said two bottles were thrown during the game - one from each set of supporters.

The club will now work with Police Scotland to identify those involved in the "unacceptable" behaviour which put "players and others at risk".

A spokesperson from Hibernian F.C. said: "We will review the CCTV footage and work with the appropriate authorities to identify those involved in throwing items onto the pitch.

"We understand two bottles were thrown, one from each set of supporters. This is entirely unacceptable and puts players and others at risk.

"The match was a good game, played in a great spirit, but unfortunately yet again the headlines will be around this kind of unacceptable conduct."

A flare was also thrown onto the field after James Forrest's goal put the visitors ahead.

Celtic interim boss Neil Lennon said: "It is a sore point of this season, whether it be bottles, coins, flares.

"It is just totally unacceptable.

"That should be safe environment for the players, they are entertaining the public, whether the Celtic public or the Scottish public.

"Officials, management; that should be a safe environment for us to come and work and enjoy our work.

"I don't like to see it. It has got to be stamped out. It just happens far too often.

"That could really have hurt Scott and if it had, god knows what we would be talking about now.

"It must be a social thing, I don't know. It is not on. We need to find the culprits, arrest them and punish them."

Lennon's successor at Hibs, Paul Heckingbottom also condemned the incident.

The former Leeds boss said: "No one wants to see it. Wherever it has come from, we need to find whoever has thrown it."

A Police Scotland spokesperson told STV News that the incidents will form part of a post-match inquiry.
