The Football Association (FA) have contacted Birmingham City for an explanation after objects were thrown on to the field during the Blues' win over Swansea City last weekend.

The game at St Andrew's was interrupted in the second half as Swansea goalkeeper Lawrence Vigouroux complained that missiles were being thrown from the crowd.

Birmingham have now issued a statement saying "the actions of a very small minority cast a shadow over" their 2-1 win.

"Several objects were thrown onto the pitch from the Tilton End. This is completely unacceptable. There is no place for this behaviour at Birmingham City Football Club," the club said.

"The incidents were reported by the referee to the Football Association who have contacted the club for an explanation of the events. The club is working closely with the police and assisting them with their enquiries.

"We will support the police with its investigations to ensure the appropriate action is taken against anyone who is identified to have broken the law."
