A 68-year-old non-resident Indian was allegedly assaulted, gagged and bound by two unknown accused on Wednesday.
They fled with cash and valuables worth Rs 1.5 lakh. Police suspect the robbery may have resulted from a personal dispute.
D N Nagar police station officials said this happened on the first floor of newly redeveloped Shabnam building near the Juhu Galli area.
The victim, Pramila Rao, who lives with her daughters in New Zealand, has been in the city since December last year.
She was alone in the flat on the night of the incident, officials added.
Police records say the accused entered the flat through the balcony, pinned Rao down, bound her hands with a sari, and gagged her.
They fled with her cellphone, gold jewellery, cheques and a passport kept on the table.
Police sources said that after the accused left, Rao crawled to her kitchen and freed herself with a knife she found there.
Rao suffered minor head injuries and has a swollen face after the two men repeatedly slapped and punched her on the head and face, officials added.
“The injured Rao crawled to kitchen, freed herself and screamed for help,” said a neighbour.
Police suspect the assault and robbery could be due to a personal dispute Rao had with a relative in Bangalore, when she went there around two weeks ago.
“The accused have taken her passport, air tickets, and cellphone, apart from the ornaments, which suggests robbery was not the primary motive,” said Senior Police Inspector M.D. Awahad of D N Nagar police station.
