Hearts owner Anne Budge was among those evacuated from the main stand because of a fire alarm before last Saturday’s game against Hamilton

Hearts are facing questions over the safety of their new main stand at Tynecastle after problems which led to delayed kick-offs at recent matches.

Police Scotland have written to Edinburgh City Council’s public safety department over “significant concerns”.

Kick-off was delayed for their first match back against Partick Thistle on 19 November over a turnstile issue.

A fire alarm triggered by a kitchen sensor caused another delay before last Saturday’s game against Hamilton.

There were also problems with the floodlights during the 0-0 draw with Ross County on 25 November, caused by the electricity supply.

Hearts were given a temporary occupation certificate only on the morning of the Partick game after a last-ditch scramble to finish redevelopment work, which was originally scheduled to have been completed by early September.

The certificate has been re-issued on a match-by-match basis since, with the club confident a new one will be issued on Friday before Saturday’s Premiership game against Motherwell.

The new main stand at Tynecastle first opened on 19 November

Hearts are in the middle of a run of six home games in a row at Tynecastle, having played nine of their first 13 league games away from home because of the delays in redeveloping the main stand.

After the Motherwell match on Saturday, they are scheduled to host further games against Dundee on Tuesday, 12 December, and Celtic on Sunday, 17 December. They also face city rivals Hibernian at Tynecastle on 27 December.
