A Bengaluru Bonnie and Clyde? Police have arrested a city techie and her male friend in the Andamans days after she killed her mother and stabbed her brother before leaving him for dead.

Here's what happened, according to a report by The Bangalore Mirror:

- Early on Sunday morning, a woman techie murdered her mother, 54, and stabbed her brother. She incorrectly assumed she had killed him, and left.

- He would later tell investigators about his sister's bizarre explanation: she owed lakhs to debtors and didn't want them to hound him or their mother.

- But the police are now looking at a different motive: a relationship. The techie was found with a male friend in a hotel in Port Blair, capital of the Andaman and Nicobar Islands. Both were arrested.

- The Bengaluru police used surveillance camera footage -- which showed the techie and her friend on a bike -- and worked with their counterparts in the islands to track them down.

- The police suspect the woman's mother and brother didn't support her relationship with the man. They plan to grill the suspects for more information.

- They say she plotted the murder weeks ago and purchased tickets to holiday with her friend.

- The suspects will be brought back to Karnataka today.
