A couple from Ambernath township in the district was killed when a water tanker hit their motorcycle, the police said today.
The police, however, registered a case under IPC sections for murder and criminal conspiracy against four people, including the tanker driver, as they suspect that the incident was the fallout of a property dispute between the couple and the accused.
The tanker driver was arrested in the wee hours today, Hill Line police station inspector G H Palange said.
The couple - Vasudeo Balue Shendre (50) and his wife Rekha Shendre (40) - was going towards Balegaon on the two-wheeler last evening when a water tanker hit their vehicle from the rear end at Narhen village, killing both of them on the spot, he said.
The police registered a case against the tanker driver and three other people, all residents of Ambernath, and launched a search for them, Palange said.
The police suspect that the couple was killed over a land dispute between them and the accused, he added.
