Police investigators are searching a garden shed in Surrey which may have been used as a bomb factory in the terror attack on the London Underground last week, according to a report.
The Times newspaper said that counter-terror experts have taken an interest in an outhouse building in Sunbury-on-Thames, a suburb just west of London, Britain.
The property, which on Tuesday morning remained behind an imposing metal police cordon, is the home of two foster parents whom media reports have said helped care for both men arrested since the attack on Friday.
The Times, citing unspecified police sources, said the shed could have been used by the younger of the two suspects, an 18-year-old who was arrested at the port of Dover the morning after the attack.
A spokeswoman for the Metropolitan Police declined to confirm the story to Business Insider. She said the press office would not ordinarily provide this detail on a live investigation.
The apparent police interest in the shed comes two days after CCTV footage recorded just outside the house was obtained by ITV. It shows a man carrying an item which strongly resembles the bomb used.

The explosive went off on an eastbound District line service at Parsons Green station at around 8:20 a.m. on Friday last week, injuring 30 people.
Security experts have suggested that attack was botched, and could have killed dozens of people had its payload – potentially a chemical compound known as TATP – detonated with full force.
Officers continue to question both the 18-year-old and a 21-year-old, who has been named in the media as Yahyah Farroukh, a Syrian refugee who worked in a west London chicken shop.
The Metropolitan Police has been given permission to hold the men without charge beyond the usual 24-hour limit under laws which give officers extra powers to hold terror suspects for as long as 14 days.
