THIS WEEK IN 1991: Homes evacuated in gas blast scare

Have your say

Families were evacuated from their Portsmouth homes when a gas leak threatened to blow up a block of 20 flats.

Fire fighting crews from across the city were on stand-by in case of a major explosion from Grosvenor House in Grosvenor Street, Southsea.

Residents were led to safety as British Gas Southern engineers cut off the main gas supply and spent more than six hours tracing the leak.

The gas was discovered seeping from a service pipe to the building.
