Chennai police arrested two men, identified as Dawood (41) and Salim (38) at 8.30 pm on December 7 in Korukkupet of North Chennai. The duo were accused of trespassing into an apartment at Korukkupet. Police control room received a distress alert made through Kavalan app and the message was traced to R K Nagar. The two men in the house were secured by police after the woman in the house – Anita Surana (47) – informed the police that the men barged into the house claiming to be courier delivery boys. She had installed Kavalan SoS application on her phone after reading about it in newspaper. She used it when the men entered the house sensing danger. This is the first arrest using ‘Kavalan SoS’ mobile phone application (Kavalan in Tamil means protector). The app is meant to help women in distress. However, the men had allegedly insisted that they had come to the right place and an argument ensued which made Anita to press the distress button. The men reportedly pressed one digit of a massage parlour phone number wrong and the call went to Anita. The woman who mistook the caller for the courier boy gave him the directions over the phone. Dawood and Salim were remanded to judicial custody. It is to be noted that Dawood, a relative of Salim, hails from Myanmar.
