MADRID: Spain's Interior Ministry says police have arrested a Pakistani man suspected of promoting terrorism and spreading propaganda on social media networks.

A ministry statement the 25-year-old resident of the northern Catalan city of Lleida was part of a cell partially dismantled with the arrest of three Pakistani brothers in Lleida last year.

The ministry said the man detained Tuesday had become more engrossed in radical activities in recent weeks.

Sixteen people were killed in attacks in the Catalan capital, Barcelona, and another Catalan coastal town last month. The Islamic State armed group claimed the attacks.
