Three employees of a company were arrested on Thursday in connection with the collapse of a portion of an under-construction bridge near the international airport in Mumbai in which three people were killed, police said.

The arrested -- Pechi Muttu Subramaniam (27), Subbaya Velu Shravanal (34) and Lakhbir Nirmal Singh (27) -- were supervisors of the site and employed with Larsen and Toubro, which had taken up the construction work of the bridge, they said.
