Police have launched a criminal investigation after a Hearts fan lunged towards new Celtic signing Scott Sinclair following his late winner at Tynecastle.

Footage of the goal celebration shows a fan standing up and moving his arms towards Sinclair as the winger celebrated his debut goal by running along the track in front of the Roseburn Stand towards the away supporters. There did not appear to be any contact.

A Police Scotland statement read: "Police in Edinburgh are investigating after a supporter attempted to confront a Celtic player within Tynecastle Stadium on Sunday 7th August."

A statement from the Edinburgh club added: "Hearts is aware of an alleged incident following a goal scored by Scott Sinclair during the Celtic match at Tynecastle on Sunday 7th August.

"The club have been in discussion with Police Scotland and this matter is now the subject of a criminal investigation.

"The club will work with the police and share all relevant information as necessary."

Sinclair was booked for running into the Celtic supporters to celebrate his goal, which came hours after he completed his transfer from Aston Villa.

A Hearts fan was jailed for eight months for breach of the peace in 2011 after running out of the main stand at Tynecastle and launching himself at then-Celtic manager Neil Lennon in the technical area.
