Milan, May 14 - A pensioner died in hospital on Tuesday after being attacked with a pickaxe by a Ghanian migrant in Milan last weekend, taking the death toll of the rampage up to three. Ermanno Masini, 64, was walking his dog when he was attacked by Mada 'Adam' Kabobo early on Saturday. Alessandro Carole', an unemployed 40-year-old who was attacked outside a cafe, was killed on Saturday and 21-year-old Daniele Carella was declared brain dead on Monday after being targeted too. Two other people were injured in Kabobo's hour-long string of attacks in Milan before he was stopped by police. Kabobo reportedly suffered from mental problems and told police "I never sleep". The Ghanian, who has a criminal record, came to Italy illegally in 2011 and was later served an expulsion order but this was suspended pending his appeal.
