A post-mortem examination has established that she died as a result of head injuries.
The man arrested now, Nagaraja Kumar Nalluri, also an Indian student, had sustained injuries in the incident on Tuesday. He was discharged on Thursday from a London hospital.
He has been charged with murder and will appear before the Birmingham Magistrates Court on Friday morning, officials told PTI.
The police have not released any further details about the incident.
Jyothirmai's neighbours told the media that it seemed like it was a fight between two persons and while four people were living in the house, only two persons were seen there at the time of the incident.
Times of India reported that Nagaraju, who hailed from Jeedimetla in Andhra Pradesh capital of Hyderabad, had also gone to the UK from the same agency, Overseas Education4u, through which Jyothirmayi went to pursue her MSc in Public Health. Both belonged to the same batch of September 2007.
This is the second incident of murder involving an Indian in the Birmingham area in the last three years.
In November 2005, Anurag Johri, a Lucknow-born Indian PhD student at the University of Central England Birmingham, battered his wife, Deepti Anurag, 29, to death because she had left him. He is currently serving a life term in a British jail.
The sensational murder of Deepti was dubbed a 'Google murder' because Johri, 34, did an internet search on how to kill with a baseball bat before killing her.
