The London Bridge attackers were unlikely to have become more aggressive as a result of taking bodybuilding steroids, an inquest has heard.
Three terrorists mowed down pedestrians on London Bridge and ran amok around Borough Market with 12-inch ceramic knives on June 3 2017, killing eight people and injuring 48 others.
The attackers – Khuram Butt, 27, Rachid Redouane, 30, and Youssef Zaghba, 22 – were shot dead less than 10 minutes after the rampage began.
Toxicologist Professor David Cowan rejected the suggestion they had been “juiced up” on steroids, making them more aggressive.
Jonathan Hough, QC, counsel for the coroner, asked: “What is the chance of the use of steroids affecting one or more of them behaviourally?”
Prof Cowan said DHEA, an anabolic steroid, was more likely than not administered to the attackers.
