Manchester United have doubled down on security at their Old Trafford stadium after last night's terror attack at the nearby Manchester Arena.
The club's Megastore, Museum, Red Cafe and Stadium Tour are all closed to the public today.
A BBC journalist also tweeted that he was greeted by metal detectors on the Old Trafford forecourt on his way to work this morning.
Meanwhile the club's players have had their cars checked for bombs this morning as security staff moved to ensure no repeat of last night's atrocity.
United have asked for permission for players to wear black armbands during their crucial Europa League final against Ajax in Stockholm tomorrow night.
Twenty-two people, including children, were killed last night when a lone terrorist detonated what has been described as an improvised explosive device at the end of a concert by US singer Ariana Grande.
The bomb was detonated in the foyer as fans made for the exits at the end of the concert. Witnesses reported scenes of utter chaos as people climbed over each other to escape.
