London 7/7 bus bomber Hasib Hussain was told off about his manners on the day he detonated a suicide bomb on board a number 30 bus in Tavistock Square.

The 7/7 inquest was told yesterday that he kept barging into other passengers with his lethal backpack aboard a number 91 bus along Euston Road.

Canadian Paul Rekret told the hearing: “A woman in her 20s tapped him on the shoulder and politely asked him to be careful because he was hitting an elderly woman and perhaps others.”

“He simply did not react. I thought he was a lost and anxious tourist. He was behaving very oddly.”

PhD student Aneta Dybek-Echtermeyer, who was standing next to Hussain, said people became angry with the 18-year-old.

“He was punching them all the time with his backpack. It was big and heavy.

“He looked exhausted. Sweat was dripping down his face.”

Evidence already heard by the inquest into the 2005 atrocities suggested that Hussain planned to set off his bomb on the Underground at the same time as his fellow terrorists.

But it apparently failed to go off and he was captured on CCTV emerging from the Tube at King’s Cross station and joining the throng of commuters evacuated after the initial blasts at about 8.50am.

CCTV footage shows Hussain rummaging in his explosive-filled rucksack outside a WH Smith store in the station and then buying a replacement nine-volt battery for the device.

Police believe Hussain inserted the new battery into his bomb in a nearby branch of McDonald’s.

Sitting at the back of the upper deck, he blew himself up at the junction of Tavistock Square and Upper Woburn Place at 9.47am.

The blast was so loud that some emergency workers deep underground rescuing victims of the King’s Cross Tube attack thought it might be a secondary explosion on the train.
