London, Nov 19 : The British couple, which was caught having sex on a Dubai beach, may have their sentence quadrupled if their appeal boomerangs.

Michelle Palmer, 36, of Oakham, Leics, and Vince Acors, 34, of Bromley, Kent, were sentenced for indecent behaviour in a public place after a policeman caught them romping at the Jumeirah beach in Dubai.

The duo had recently challenged their conviction and three-month term, reports The Sun.

But now, prosecutors have counter-appealed, insisting that their sentence should be extended to a year.

The decision on the case will be announced on November 25. (ANI)
