However, despite repeated queries by the media, no one from the state police confirmed or denied it.The state's DGP has urged the Muslims to hold Friday prayers in their homes instead of mosques.The police chief further said that the 11 Tablighi Jamaat members against whom an FIR was registered at Nerwa Police Station in Shimla district on Wednesday had not attended the congregation.They had come from Misarwala village located in Paonta Sahib Tehsil of Sirmaur district, he added.The 11 were booked under sections 269 (negligent act likely to spread infection of disease dangerous to life) and 188 (disobedience to order duly promulgated by public servant) of Indian Penal Code at Nerwa Police Station.They arrived in Nerwa in Shimla district from Paonta Sahib in Sirmaur district to go to their homes in different villages amid a curfew, a Nerwa police officer said.Eight of them are residents of Kima Chandrawali village whereas two are residents of Bharanu village. The driver Shabeer is a resident of Paonta Sahib, he said.All of them have been quarantined in Panchayat Bhawan, he added.Stressing that religious leaders should not hold functions or gatherings, Thakur directed the officials to take strict action against violators.The chief minister also asked all DCs and SPs to hold meetings with religious leaders and disseminate their recorded messages to motivate people of their respective communities to avoid religious gatherings and celebrations to check the spread of COVID-19.
