Belgian prosecutors call for details on new terror suspect

Belgian prosecutors appealed to the public Monday for information about a man who allegedly traveled to Hungary last year with the Paris massacre suspect who eluded capture for months.

The federal prosecutor's office said in a statement that they are seeking details about 24-year-old Najim Laachraoui, who is said to have traveled to Syria in February 2013, according to The Associated Press.

It said Laachraoui was checked by guards at the Austria-Hungary border while driving in a Mercedes with two people including the attacks suspect Salah Abdeslam, who was captured in Brussels on Friday. Laachraoui was one of two men using fake Belgian identity cards who were with Abdeslam when passing through the checkpoint on Sept. 9, the New York Times reports.

Laachraoui is said to have rented a house under the name of Soufiane Kayal in the Belgian town of Auvelais which was allegedly used as a safe house. Prosecutors said traces of his DNA were found there.

Laachraoui’s DNA and Abdeslam’s fingerprints also were found by authorities at a house on Rue Henri Bergé, in the Schaerbeek section of Brussels, the New York Times reported.

Authorities searching the Rue Henri Berge property on Dec. 10 found traces of TATP (triacetone triperoxide), the signature explosive for Islamic State terror operations in Europe and an ingredient in suicide vests used in the Paris attacks, according to the newspaper.

Laachraoui appears to have studied electromechanical engineering at a Catholic high school in Schaerbeek, graduating in 2012, an alumni newsletter said.

In addition to Laachraoui, authorities also are searching for Mohamed Abrini. The 31-year-old was seen in a video traveling with Abdeslam on Nov. 11, two days before the Paris attacks, at a gas station along a highway to the French capital.

The Nov. 13 attacks in Paris left 130 people dead.
