Chatto, who was found tied to a tree by a red sari, was wearing a red blouse and a red petticoat.

Her husband, who was a driver in an export firm here, was found hanging from a nearby electric pole.

The bodies had injury marks and 'it is still a mystery', said Noida district police chief Ashok Kumar.

'We cannot claim a suicide... nor are we in a position to say it is murder. We are waiting for the autopsy report,' he said.

A police team has been sent to Pilibhit also.
