The Maharashtra Anti-Terrorism Squad (ATS) has found a note referring to "lone wolf" attacks and the Islamic State at the house of a 31-year-old man arrested for allegedly attacking two security guards after asking their religion in Thane district, news agency PTI reported, quoting officers on Tuesday.

Prima facie, the incident appears to be a "lone wolf" attack carried out by a radicalised man, who allegedly asked the guards to recite the 'Kalma' before stabbing them early on Monday, an officer said.
