Neil Lennon, linesman and goalkeeper attacked at derby
Five arrests after Hearts v Hibs, including one man for attacking the assistant referee.
A football fan has been arrested for allegedly attacking a linesman at the Edinburgh derby.
Assistant referees, Frank Connor and David McGeachie, were both said to have been struck by objects during the Hearts v Hibs match on Wednesday.
A 25-year-old man has been arrested in connection with one of the incidents.
Police arrested five fans during the game, which finished 0-0.
Hibs boss Neil Lennon was struck on the jaw by a pound coin moments after appearing to celebrate Hearts having an injury-time goal disallowed.
Hearts keeper Zdenek Zlamal was also "punched" by a fan during the match.
Officers are also investigating both incidents.
Chief inspector Murray Starkey said: "Police Scotland condemn the mindless acts of violence which included missiles being thrown during last night's Edinburgh derby.
"I can confirm we are investigating two separate incidents involving the Hearts goalkeeper and the Hibernian manager during the match.
"A 25-year-old man has been arrested and charged in relation to an assault involving the assistant referee. A total of five arrests have been made.
"Anyone who witnessed these mindless acts should contact the police on 101."
Hearts owner Ann Budge said: "The only thing we can do is retrospective and that is using the CCTV to identify the individuals and asking our supporters, and this happened last night which is good, to speak up if they see something of this nature happening."
Hibs chief executive Leeann Dempster added: "Irrespective of what a manager does track side he does not deserve to be hit by an object and if others or the league deem any manager's antics to go beyond the realms of what is acceptable then that will be dealt with."
