Glasgow police have launched an investigation after a "suspicious package" arrived the home ground of the Celtic football club, a day after the team's manager Neil Lennon was attacked during an away match at Hearts.
One news report claimed the package contained a bullet and was addressed to Lennon, who has been a target for sectarian hatred all season.
Earlier this week in Edinburgh police arrested a fan who emerged from the main stand and charged towards Lennon, who has been subjected to death threats and attempted parcel bomb attacks in the past.
