Give him the Ooh la la

And then read him his rights;

An alleged jewellery store robber who says he kissed a hostage out of compassion was tracked down through his DNA, a Paris newspaper reports.

He and another man were said to have seized an employee of the store in the French capital last April, holding her in her home, says Le Parisien.

Tying her up, they poured water on her, saying it was petrol, and threatened to burn her if she did not co-operate.

Detectives later traced the DNA from the woman's cheek to the suspect.

Now in prison in the south of France for separate offences, the suspect, 22, said he had kissed her to "relieve her trauma", an unnamed police source told Le Parisien.
