A Polish mum is suing an Egyptian hotel after claiming her daughter got pregnant using their mixed swimming pool.

The bizarre claim surfaced as Magdalena Kwiatkowska demanded compensation after her 13-year-old daughter came back from the family holiday expecting a baby.

Tourist authorities in Warsaw confirmed they had received the complaint which states that the girl conceived because of stray sperm in the pool.

“The mother is adamant that her daughter didn’t meet any boys while she was there and is determined to go ahead with the case,” said one travel industry source.

It will be interesting to see if the baby’s genes come from the shallow end or the deep end of the pool.
