A 23-year-old man and a 14-year-old boy have been questioned in connection with a major fire at a secondary school.
The school's drama block is now due to be demolished
The pair - arrested on Tuesday - have been released on police bail by officers investigating the suspected arson at the school in Thame, Oxon.
The fire on Saturday destroyed Lord Williams's secondary lower school's drama block, which is to be demolished.
A 22-year-old man, who had already been arrested and bailed, has been recalled to prison as he was on licence.
Det Sgt Alan Clements, of Thame CID, said: "We have viewed the CCTV from the incident.
"There's a strong possibility of further suspects being involved in this arson, and we need the public's help to identify who they are."
The pair are now on police bail until 13 August.
