Cadac gas bottle caught fire

We went camping in Worcester over the past weekend, my husband placed the cooker topper onto the Cadac Gas bottle to boil water for coffee, within 5 minutes the gas bottle was on fire, after a huge struggle they eventually threw the bottle in the river, because they were not able to put the fire out. we had children around and our first thought was that the bottle will explode, this could have ended very tragically. we took photos of the gas bottle and we are in position of the damaged bottle. we would like for someone to make contact with us in order to collect the gas bottle and to ensure that this does not happen to someone else.
