The wounded man was allegedly attacked by members of a rival group, as happened a week ago when a young Spanish national died after being stabbed in the Villaverde district
Two boys, aged 15 and 25, were stabbed to death and another 17-year-old was also seriously injured by a knife in three events that occurred in Madrid in less than an hour
When the suspect's accommodation was searched, a number of items were found that could refer to Islamist propaganda material, and the suspect himself had spoken of his 'contribution to the Jihad'
