Condemning the attack on a CPM MLA's daughter in Mangalore as "heinous", the BJP said on Saturday that there was a need for a thorough inquiry into the incident.

"This particular incident needs to be investigated thoroughly. The facts which are emerging indicate that there may be a different story altogether," BJP spokesperson Rajiv Pratap Rudy said.

Activists of a suspected saffron group dragged the daughter of a Kerala MLA and her accompanying male friend out of a bus on Friday in Mangalore and reportedly kidnapped them before releasing the victims.

Describing the yesterday's incident as "heinous action, Rudy said political parties should not accuse BJP of any involvement in such cases.

"Imputing BJP every time to any such instance anywhere would have political designs as you are aware that the next general elections are round the corner," he said.

"The BJP condemns this incident in severest terms. This is unacceptable to us. Any action by any group, individual or organisation having any political or social affiliation is unacceptable and needs to be condemned in severest terms," fumed Rudy.

He demanded that the Karnataka government and whichever "other organisations" interested must look into the case directly.
