The probe comes after anti-board posters were put up close to the homes of chairman Peter Lawwell, CEO Michael Nicholson, chief finance officer Chris McKay and head of security Mark Hargreaves.
Police are investigating an “intimidation” campaign against Celtic directors and their families, the Sunday Mail can reveal.
It comes after anti-board posters were put up close to the homes of chairman Peter Lawwell, CEO Michael Nicholson, chief finance officer Chris McKay and head of security Mark Hargreaves.
The club has criticised the “disgusting and cowardly” attacks and claimed the school of one of the staff members’ children has also been targeted.
A Celtic spokesman said: “We can confirm that a targeted attempt has been made to intimidate Peter Lawwell, Michael Nicholson, Chris McKay, Mark Hargreaves and their families.
“A number of posters similar to those we have seen this season have been posted in the vicinity of the homes of Peter, Michael, Chris and Mark.
“These signs have also been posted at a school attended by one of their children.
“This is a disgusting and cowardly attempt to intimidate and threaten Club staff and their families.
“We are aware that Police Scotland is investigating these incidents.
“The Club is firm in its resolve not to give in to this type of intimidation.”
In November Celtic’s AGM was abandoned after only 25 minutes as a result of heckling from supporters towards board members.
Shareholders unhappy with the way the club are being managed held up red cards, booed and chanted “sack the board” as directors arrived.
Ross Desmond, the son of Celtic’s principal shareholder, Dermot, read out a statement that criticised supporters for their treatment of the leadership.
He said: “Our board, led by Peter Lawwell, and our executive, led by Michael Nicholson, are dedicated Celtic people. The attempts to dehumanise them and vilify them are shameful.”
Fans have also been holding up banners protesting against the board during games.
Celtic reached the knockout phase of the Champions League last season, but supporters have criticised their approach to the summer transfer window.
Brendan Rodgers resigned as the manager in late October, with Frenchman Wilfried Nancy appointed as his replacement last week.
Last week the club extended their ban on the Green Brigade fan group due to “safety incidents” which they say include threats against the club’s head of security.
Celtic also indicate that any evasion of the suspension could threaten the continued use of rail seating / safe-standing which has been in place at Celtic Park since the summer of 2016.
An initial six-game ban was imposed on around 200 people in early November following “violent and threatening behaviour” at a home match against Falkirk on 29 October.
Celtic have said the block on the group’s season tickets will continue until they are “satisfied that the Green Brigade will engage in the safe operation of the stadium, which is critical for the continued operation of the entire rail seating section.”
The club also state that two members of the Green Brigade “directly threatened” and “sought to intimidate” their head of safety and security operations Mark Hargreaves.
A spokesman said the ban was “entirely unrelated to any protests or banners” amid anti-board sentiment.
