Police in Palghar Wednesday questioned a young man for allegedly posting on Facebook objectionable matter against MNS chief Raj Thackeray, official sources said.
However, a police official from Palghar, declining to be identified, said the "youth had neither been detained nor arrested, but was merely being questioned" and no offence has yet been registered in the matter.
Identified as an 18-year-old meat shop assistant, Sunil Vishwakarma was picked up Wednesday for quizzing by police after some Maharashtra Navnirman Sena (MNS) activists complained of objectionable matter allegedly posted under his name on networking site Facebook.
According to initial investigations, it was found that Vishwakarma was unable to operate Facebook and police suspected someone might have created his fake profile, pointing to hacking.
The official said the matter was beyond the purview of the Palghar police and would be transferred to the Thane police's cyber cell for probe and action.
With the recent Facebook controversy involving two Palghar girls -- Shaheen Dadha and Renu Srinivasan -- still fresh in the minds of the police, they are dealing with the matter with extra caution.
Vishwakarma "has been kept in the police station to protect him from possible attacks" as police probed the issue, the official said.
Meanwhile, Palghar, around 100 km from here, and its surroundings observed a shutdown following a call by the Shiv Sena.
The shutdown was in protest against the departmental inquiry against and suspension of superintendent of police (Thane rural) Ravindra Sengaonkar and Palghar police chief senior inspector Shrikant Pingle in the Dadha-Srinivasan Facebook case.
With a population of around 200,000, Palghar is a sprawling semi-industrialised and tribal dominated, eco-sensitive region in north-west part of Thane district, which is soon to be carved out as an independent district.
