Noida police have detained Vishnu, the former domestic help of the Talwars, with regard to the Arushi murder case.Vishnu was the one who had introduced Hemraj to the Talwars eight months ago.

Police sources have told NDTV that till 2007, Vishnu used to keep a replacement during his two months annual leave and get back to his job when he returned. However, after Hemraj was hired, Vishnu did not get his job back and this could be the possible reason for his grudge.And another startling revelation came to the fore on Monday morning by Bharti, the Talwar’s part-time maid.

‘’I came in the morning. I rang the bell several times. The gate was locked from outside and madam gave me the keys from the balcony. Then I opened it,'’ said Bharti.The case that made national headlines has seen many theories and flip-flops by the police.

On Day one, that is last Friday, the police named domestic help Hemraj as the prime suspect because he was missing.

However, the very next day, Hemraj’s body was found on the terrace of the house and the police said a third person might have been involved.

Then, they spent the entire day three questioning Arushi’s parents and said all previous domestic helps who had worked for the Talwars were suspects
