A 27-year-old woman from Hyderabad, Kontham Tejaswini Reddy, who was pursuing higher education in London was murdered at her residence in Neeld Crescent, Wembley, at around 10 a.m. (BST) on Tuesday.
A cousin of Tejaswini in Hyderabad, identified as Vijay, said the accused was a Brazilian man and had moved into the shared accommodation - where Tejaswini lived with her friends - less than a week ago. Tejaswini had reportedly gone to London in March last year to get her Masters degree, NDTV reported.
The UK Metropolitan Police, on its website, announced the arrest of a 23-year-old Brazilian man as a suspect in the murder and an investigation was underway.
"Two people, a 24-year-old man and a 23-year-old woman, were arrested at the scene on suspicion of murder. The man remains in custody. The woman has been released without further action," an earlier statement from the police said.
Detective Chief Inspector Linda Bradley, from the Met's Specialist Crime Command was quoted as saying, "This has been a fast-moving investigation and I would like to thank the public for sharing our appeal for information about this man. He is now in custody. "
She further said, "I recognise the significant concern this incident has caused in the community and I would like to reassure the public that a dedicated team of detectives are working to establish what happened. Local officers will remain in the area over the coming days to respond to any concerns."
A post-mortem examination will be scheduled in due course, the police also said.
