The Sun/BBC have picked up a letter from the police to the city council...

“At present, I have concerns over the public safety of patrons attending football matches at Tynecastle Park.

“Given the incidents in the previous three matches I now have significant concerns over the reliability of electrical systems within Tynecastle Park.

“Electrical failings impact on public safety with evacuations and delayed kick-offs as evidenced in recent matches.”
