Gas leak!!

Lots of police, fire brigade and ambulances in our street this afternoon. It all started around 14.00  pm.
There's a gas leak somewhere. A gas smell everywhere.
Several house have been cleared. We went away as well.
It turned out that gas leaked into the sewer very near to our home.
Once the problem was located, the street was re-opened again and the leakage was fixed. By then it was 21.30 hours.
Soon after everybody was gone, our street went into it's usual 'sleepy-mode' again.
