Priyam Shrivastava on February 13, celebrates birthday with his flatmates

The Navi Mumbai Crime Branch probing the mysterious murder of 28-year-old engineer Priyam Bharti Shrivastava are looking for answers from his colleagues to two main questions - firstly, why did they call him to a different place (Belapur bus stand), when they knew he was coming by cab, rather than asking him to come directly to the restaurant they were having his birthday lunch at, and secondly, with whom was he talking on the phone while entering the restaurant and did he mention anything about his ill health to that person.
