The thieves broke into Barnet Hospital in north London last night and tampered with the machine, which is inside a staff restaurant.
Hard-working medical staff at the hospital have been battling to look after coronavirus patients. In Barnet alone, 81 people have tested positive for Covid-19.
The Royal Free London NHS trust tweeted: ‘Our staff restaurant at Barnet Hospital is open as normal this morning despite someone breaking in last night to steal the ATM.
‘We have no words! Police are aware. #togetherwecan.’
Barnet MPS posted earlier today saying: ‘We were called at around 2am to a restaurant area broken into at Barnet hospital in Wellhouse Lane.
‘An ATM was tampered with; we await confirmation of cash or any other property stolen during the burglary. NorthWest BCU investigating.’
