Neighbour: Police are searching the flat of Dutch architect Vincent Tabak
Vincent Tabak, 32, is registered as living at the address with his girlfriend.
Officers erected scaffolding around the property earlier today hours after it was announced that a suspect, 32, had been arrested in connection with the case.
Bristol and Avon police have not named the man, who is being held at an undisclosed location.
Soon afterwards specialist search teams moved into the neighbouring flat to where Miss Yeates lived at 44 Canynge Road in Clifton, Bristol.
Calls to Mr Tabak's employer were today being referred to Avon and Somerset Police.
Following the announcement of the arrest this morning, Canynge Road in Bristol was cordoned off by detectives and police teams descended on the Victorian mansion which contained her basement flat.
The tarpaulin was used to obscure the movements of the crime scene investigation team as they worked at the rear of the property.
Police refused to give any further details as to where or exactly when the suspect was arrested but Detective Chief Inspector Phil Jones, the senior investigating officer, said: 'I would like to thank the public for their continued support for the investigation and the information they have provided to us.
Breakthrough: Police have arrested a man on suspicion of Joanna Yeates's murder
Today Jo's father David Yeates said he was pleased that the investigation had moved forward.
Standing with his wife Teresa at their home in Ampfield, Hampshire, he said: 'Both Teresa and I are very pleased an arrest has been made and the investigation is moving forward.
'Police informed us this morning before they made the announcement about the arrest and other than that we do not know much more.
'We are optimistic about the progress, but we have not been told the name of the person who has been arrested.'
It is understood that police have withheld the name of the arrested man because of the media frenzy that followed the first arrest in the case, that of Jo's landlord Chris Jefferies, 65.
There are strict instructions on what media outlets can and cannot report during police investigations and it is understood that investigators were extremely unhappy with some coverage that they felt overstepped the mark, potentially jeopardising their enquiries.
