The parents of Tanja Morso, girlfriend of Vincent Tabak, confirmed their daughter was in a relationship with the ”lovely Vincent”.
Geoffrey Morson, the father of Tanja Morson, said he had not heard from his daughter.
Speaking on the driveway of his large, detatched home in Cambridge, Mr Morson claimed he had no knowledge of a recent arrest.
He said: ”We are a very close family and I speak to my daughter all the time but she has not told me anything. I do not know if he [Vincent Tabak] is her boyfriend or not.
”He’s a boy’s, she’s a girl and they are friendly with each other.
”Obviously this is a murder investigation and the public have the right to know about it but I don’t know any more than I have read in the newspapers.”
His wife Elizabeth added: ”We saw what happened to the landlord and we don’t want the same to happen to lovely Vincent.”
Police officers were yesterday in attendance at Mr Tabak’s workplace in Bath, Somerset.
Two men, believed to be plain clothed officers, removed items from the offices of Buro Happold
Staff who were approached outside the tall building, situated by the River Avon, refused to confirm whether they knew the 32-year-old.
A marked police van and at least one unmarked police car were parked in the staff car park throughout the day.
The car park, to the right of the building, was sealed off with cones and white signs reading: This car is reserved for Buro Happold staff only.
The signs were moved by a young male staff member to allow police or other employees to pass.
Mr Tabak refused to comment on the case when he was contacted about the Jo Yeates case shortly after Christmas. He hung up the phone when contacted by a journalist.
Police yesterday searched Vincent Tabak’s flat – which is adjoining the property Jo Yeates lived in.
