Haverhill Arts Centre has been left without internet and telephone connections following a lightning strike on Sunday evening.
The centre was hit at about 7.30pm on July 20. Power was knocked off and visible damage was caused to the building.
No one was hurt, though a chimney at the rear of the centre was damaged.
BT has estimated the phone lines could be out of action until tomorrow, making it difficult for members of the public to contact Arts Centre staff. The centre is currently unable to take phone or internet bookings.
Monday’s sold-out performance of Bugsy Malone is set to go ahead as planned.
“We’re still collating the amount of damage caused,” said Town Clerk, Colin Poole. “We’ve had some bricks blown off the back of the building.
“The lightning struck at the very beginning of the Monty Python live broadcast. Some people thought it was part of the show. The big count down clock was on the screen showing three, two, one, and then ‘bang’.
“The staff have had training and they carried out an evacuation before they started making sure the place was secure and that the building wasn’t on fire.
“We’re currently listing the things not working. It could be a very long list.”
