Both suffered injuries and were helped to reach a hospital by a student who was walking by. The man had to undergo 15 stitches, while the woman was treated for bruises on the back.
They have alleged that some policemen passing by in a vehicle ignored their call for help.
Kamal Rathod, 39, and his wife Trupti, 29, said they were stopped on the road by the two eunuchs, who assaulted him and he fell to the ground.
"The two eunuchs assaulted me and my wife. When I tried to resist, they hit me on the head and I lost consciousness. They pulled away the gold bracelet and bangles my wife was wearing, jumped on the bike and raced away," Rathod said, at the Golden Park hospital where they were treated.
The Rathods reside at Achole Road in Nalasopara (East). The incident happened at about 10.30pm.
They said they looked around for help. After they walked some distance they reached a police post, but there were no cops on duty there. "We saw a police vehicle passing by and called out. They must have seen that we were injured and bleeding, but they did not stop," Rathod said.
At Pelhar Chowk, a teenager saw their plight and took them to the hospital. "I saw they were badly hurt and got some turmeric paste to stop the bleeding. There were no policemen in sight and passersby ignored them," said Sourabh Paul, the 19-year-old who took the couple to hospital.
Paul even managed to trace the two-wheeler belonging to the couple that was abandoned by the attackers a couple of kilometres away.
The Valiv police met the couple at the hospital two hours after the incident. "We have registered a case against two unidentified persons under section 394 of the Indian Penal Code for voluntarily causing hurt and committing robbery and are investigating the incident," said Narayan Patil, senior police inspector. He also rubbished the allegations made by the couple.
