Police have appealed for 'calm' as they continue to question a Somalian teenager arrested under the Terrorism Act.
The 19-year-old man, from Easton, Bristol, remains in custody in connection with an investigation into another local teenager Andrew Ibrahim, who is accused of attempting to make an explosive.
Forensic teams are beginning fresh searches at the new suspect's home in Bellevue Road.
An examination of a second property in nearby Mivart Street has now ended with 'nothing of any significance' being found, Avon and Somerset police said.
Assistant Chief Constable Jackie Roberts addressed a meeting of key community leaders and representatives to inform them of the day's activities.
ACC Roberts said: "That meeting was extremely important and also very positive. We are very grateful for the support we have received from the local communities. I would reiterate what was said at that meeting and appeal for calm from the local communities."
Last month Ibrahim, 19, who lives four miles from Easton in Westbury-on-Trym, was remanded in custody to await trial.
He is accused of being in possession of two home-made vests, ball bearings, nails and screws.
He is also charged with making or having an explosive - hexamethylene triperoxide diamine - with intent.
The trial is expected to take place in January next year.
