The home of Celtic chief executive Peter Lawwell caught fire in a suspected petrol bomb attack in Glasgow overnight.
A car is believed to have exploded and the blaze spread to Lawwell's property.
Lawwell and his family were asleep at the residence at the time when the incident occurred.
Police and up to eight fire engines attended the scene and Lawwell and his family were taken to a secure location after the attack.
Celtic have issued the following statement:
“We can confirm that significant damage has been caused to Peter Lawwell’s house and vehicles there, following an explosion and fire early this morning, forcing the family to leave the property.
“Clearly, Peter’s family are extremely shaken and shocked by these terrible events, but thankfully all are safe.
“We understand that Police Scotland are currently undertaking a criminal investigation.
“Peter and his family will of course receive the full support and care of everyone at the Club.”
Lawwell is leaving his role at Parkhead in the summer to be replaced by Dominic McKay.
