Tech guru who helped supply pagers to Israel went missing on day of the explosions

Rinson Jose, 39, inadvertently helped supply thousands of pagers which were modified and then exploded in a deadly Israeli attack targeted at Hezbollah in Lebanon

A tech guru who inadvertently helped Israel get their hands on pagers used to bomb Lebanon went missing on day of the explosions.

Rinson Jose, 39, is said to have played an unintentional role in supplying thousands of gadgets which suddenly exploded in a shock attack targeted at Hezbollah fighters on Tuesday. A day later, a similar attack struck walkie-talkies. Both explosions combined killed at least 37 people, injuring more than 3,000.

Israel is widely believed to be behind the blasts, although it has neither confirmed nor denied responsibility. Mr Jose is listed as the owner of a Bulgarian shell company which paid £1.3million to an intermediary as part of a deal allegedly set up by Israeli intelligence agency Mossad.

Indian-born Rinson Jose - who moved to Norway in 2015 after leaving a job at an immigration advisory firm in London - has not been seen since Tuesday, when he left on a pre-planned business trip, reports the MailOnline. His employer, Norwegian media conglomerate NHST, have not been able to get in touch with him since then, and raised the alarm with authorities on Wednesday.

Oslo police said they have launched a preliminary investigation "into the information that has come to light." There is no evidence suggesting that Jose had any knowledge about the operation which saw explosives placed in the devices. One friend of Mr Jose told Norwegian news site VG that they were shocked to discover his link to the recent events, and said: "My entire network liked him. He saved his hair for many years to be able to donate it to cancer patients. That's the kind of person I experienced him to be."

It comes after Foreign Secretary David Lammy urged Brits to leave Lebanon immediately. Mr Lammy tweeted on Thursday: "My message to British nationals in Lebanon is leave while commercial options remain. Tensions are high and the situation could deteriorate rapidly." The Foreign Office warned: "On 17 September, a number of pagers, allegedly held by members of Lebanese Hizballah, exploded simultaneously in locations across Lebanon."

The leader of Hezbollah has vowed to keep up daily strikes on Israel after missile fire was exchanged across the border from both sides following the attacks. Hassan Nasrallah described the device bombings as a "severe blow", and said: "When they detonated all these pagers their aim was to kill 4,000 human beings at the same time. This was the intention of the enemy and the level of crime they have reached. We will call them the massacres of Tuesday and Wednesday."
