Lunchtime shoppers were plunged in to darkness as a power cut hit shops in North Street.
The midday power cut forced some to abandon their shopping as they were led out on to the streets.
Accessorize and Claires were among the shops in North Street hit by the loss of power, and shoppers from House of Fraser in West Street were left standing on the pavement outside until the power came back.
One shop assistant from Accessorize said the shop had lost power for about an hour although other stores on the street hadn’t been affected.
