She is currently in custody being quizzed by investigators.
A post-mortem examination on Dr Sacharvi showed she died from pressure to her neck and that she was also assaulted.
Tests have shown Vian, a pupil at Marsden Heights Community College in Nelson, was badly burnt, but officials have not yet determined the cause of her death.
There was evidence of smoke and fire damage inside the property, Lancashire Police said.
Speaking earlier in the week, Detective superintendent Jon Holmes said: 'We are continuing to ask anybody with information about this incident to get in touch with us.
'If you were in the area and saw something suspicion, think you have dashcam or CCTV from the area or have any other information, we would ask you to contact us straight away.'
Dr Sacharvi was a junior doctor with Lancashire and South Cumbria NHS Foundation Trust's specialist perinatal community mental health team since February.

Scores of emotional tributes have poured in for Dr Sacharvi , who worked for Lancashire and South Cumbria NHS Foundation Trust
She most recently worked at its Daisyfield site in Blackburn. Paying tribute to her, perinatal lead consultant Gill Strachan said: 'Dr Sacharvi fitted in well with the team.
'She was approachable, diligent and had formed good working relationships with the team. She was empathic and well-liked by the women and families that she worked with. Her colleagues described her as very kind, brilliant and a joy to work with.
'During lockdown when Covid-19 restrictions were in place, she went out of her way to support the care of women, personally delivering prescriptions to women isolating at home.
'The team are shocked and saddened, and she will be greatly missed. Our thoughts are with family and friends at this very sad time.'

Headteacher of Marsden Heights Community College, Alyson Littlewood, said: 'We are shocked and heartbroken by the tragic deaths of Vian and her mother and our whole school is mourning the loss of two much-loved members of our community.
'Vian was an outstanding student. She had that wonderful mix of academic ability coupled with an enthusiasm for everything else that school can offer.
'She was very popular and was involved in a whole range of school activities. She was extremely supportive of her friends, was generous to all and had a smile that could fill a room.
'We were all very fortunate to have her in our lives and we will miss her on a daily basis.'
