A 51-year-old GHMC sanitation worker was brutally raped on a foot over bridge in Erragadda by an inebriated 45-year-old watchman early Friday. The survivor, en route to her duties, was threatened and assaulted before the accused fled. Police swiftly arrested the perpetrator after reviewing CCTV footage and registered a case under the Bharatiya Nyaya Sanhita.
