A Belgian prosecutor says a suicide bomber who attacked the Brussels airport left a will on a computer found in a trash can in a Brussels neighborhood.

Federal Prosecutor Frederic Van Leeuw told reporters Wednesday that Ibrahim El Bakraoui blew himself up at the airport Tuesday, March 22, 2016 in twin suicide bombings.

Investigators raided the Brussels neighborhood of Schaerbeek after the attacks and found a computer in a trash can on the street including a note from El Bakraoui saying he felt increasingly unsafe and feared landing in prison.

The prosecutor also said one person detained in one of the raids remains in custody Wednesday and is under questioning.

Belgian authorities said several people possibly linked to deadly attacks are still on the loose.

Paul Van Tigchelt, head of Belgium’s terrorism threat body, told reporters Wednesday that is why the country is keeping the terrorism threat level at its highest level, which means there is a danger of an imminent attack.

He spoke alongside prosecutors who say they are searching for at least one person directly involved in the attack on Brussels airport.
