Police in Devon are appealing for a male cyclist who may hold vital clues to a house fire in Tiverton.
Officers say he cycled past the fire in Magnolia Court before emergency services arrived, possibly more than once, and may hold vital information.
The fire started around 4pm on Tuesday and caused extensive damage to four properties.
Police and Fire investigators say it is being treated as suspicious.
A 30 year old local man was arrested in connection with the incident and released on police bail until September.
