A couple who took a DNA test to silence pub gossips who questioned the paternity of their daughter got a nasty shock.

The Czech pair, from the southeastern town of Trebic, had grown sick of constant sniping from friends.

Their 10-month-old baby girl had blond hair while they both had dark locks.

So, to end the rumours, they took a DNA test.

But the results showed that neither of them had the same genetic profile as the baby and could therefore not be the real parents.

Czech news agency CTK said it is now believed their child had been mixed-up with another in hospital.

An investigation is now underway to find out exactly what happened, where their child is - and whose baby they have been raising.
