On 24 March 2022, the EIB Group Complaints Mechanism received a complaint regarding the Bangalore metro rail project (line 6). Growthwatch, a voluntary research and advocacy institution based in India, is representing and supporting a group of affected students who studied at the Technical Training Centre for the Deaf (TTCD) in Bengaluru. The buildings of TTCD were demolished in 2019 for the construction of an underground station that forms part of the project. The association that was operating the TTCD decided to discontinue the activities of the training centre. The promoter organised the transfer of three teachers and 41 remaining students enrolled for the academic year 2018–2020 to a private educational establishment in Bengaluru.
