Why are watermelons so red and sweet?

Each and every watermelon now available in the markets of Bangladesh is so red inside and so sweet in taste that it raises suspicion. This was not the case a few years back. A few years ago it was a matter of luck to get a sweet watermelon with red inside. How did it change so drastically? Are the unscrupulous sellers injecting textile colour and artificial sweetener into watermelons to make it look red inside and taste sweet? Perhaps this is happening at the warehouses, and not at retailers' level. Already news of deaths from eating watermelon in different parts of the country is surfacing in the newspapers. The warehouses of watermelons across the country may be raided by the relevant government agency to check what really is going on. The Daily Star may also publish an investigative report on the deaths from eating watermelon.
