Vasudev, his wife Beena and their associate Moni – all hailing from Assam -- were arrested yesterday from Rithala Metro Station.

According to police, their modus operandi was that they would initially distribute pamphlets in residential areas that they run a maid placement agency.

"The pamphlet contained their mobile phone numbers and when the prospective employers contacted them, they informed that Rs 10,000-25,000 would have to be paid by the employer as commission," DCP (Crime and Railways) Ashok Chand said.

Beena or Moni used to join as a maid in the household but used to run away from there the next morning on some pretext or other.

The arrests came on a complaint by a resident of Ashok Vihar area that Bulbuli Maid Service has cheated him on pretext of providing a maid after taking a commission of Rs 18,000.

According to the complainant, the maid only worked with them for a day and then ran away on the pretext of getting milk.

Police said Vasudev came to Delhi about four years ago and had worked in a number of maid placement agencies and married Beena.
