The Chattogram Metropolitan Police has appealed to city residents to share information on extortion, intimidation and other crimes through its mobile application in a bid to curb rising incidents. The call was made on Sunday through a post on the CMP’s official Facebook page and a WhatsApp message sent to journalists. Police said complaints had surfaced that groups were using “false identities” to demand money from businesses, organisations and individuals, both openly and in secret, while issuing threats and spreading fear. The force urged city residents to report any such activity through the Hello CMP app to help police maintain security across the city. The Hello CMP app is available for download from Google Play:https://play.google.com/store/apps/details?id=com.hellocmp.design.
