The constables have been identified as Umesh Dhebe (27) and his younger brother Ramesh Dhebe, police said.
Ramesh Dhebe, attached to Quick Response Team (QRT) was allegedly caught impersonating his elder brother last month, after Umesh Dhebe decided to skip work and attend a friend's wedding, a senior IPS officer said, requesting anonymity.
Action has been initiated against both the conastables, the officer said.
The incident took place at the Police Training School in Marol on April 22, when a police recruitment drive was under way, police said.
The younger brother obliged Umesh Dhebe by turning up at Marol, the police said.
Ramesh Dhebe had donned the belt and name tag embossed with Umesh Dhebe's buckle number and full name, said police, adding that he was eventually pulled out by senior officials.
Upon being asked about he not being Umesh Dhebe, the younger brother confessed that his brother and he had switched places, since the former had to attend a meeting, police said.
Meanwhile, the outcome of the action will depend on the submission of the disciplinary action report, police said.
