A threat was made on Thursday, reportedly on social media, leading to action being taken by the Premier League club.
A statement from Leeds read: “Leeds United’s offices, ticket office, Foundation offices and club shop at Elland Road will be closed until further notice on the advice of the police.
“We apologise for any inconvenience and we will inform the public when normal service resumes.”
A West Yorkshire Police statement added: “Police were called to attend at Elland Road football stadium following reports of a security threat to the premises.
