‘I have worked in Gothenburg for over 30 years and I have never known anything like it,’ said the officer. ‘I will not let my children go into the city after 2pm and never at night.

UK Daily Mail Last year, Sweden, with a population of 9.8 million, took in more than 160,000 asylum seekers. Just over three out of every 2,000 citizens are now refugees.

The Gothenburg suburb of Mölndal is in the spotlight this week after the young, beautiful social worker Alexandra Mezher, 22, was stabbed to death in a frenzied attack at the Muslim child migrant centre where she worked.

‘We have become completely overwhelmed,’ one policeman with over 30-years-service with Gothenburg Police told MailOnline. ‘We have given up with drug crime. We just don’t have the resources.’ Instead officers are trying to fight back the explosion of violent street crime that has erupted in recent months.

‘There are 20 robberies in Gothenburg every day – usually with violence or the threat of violence. ‘This week an 83-year-old lady had a gun put in her face when she was mugged on her way to play bingo. They got away with just 50 Kroner [about £4].

It was also claimed this week police had been forced to flee after being attacked by a mob of asylum seekers as they tried to relocate a ten-year-old boy amid allegations he had been ‘raped repeatedly’ at a refugee centre.

And staff at a migrant centre in Sweden had to flee where 19 asylum seekers ran riot with weapons.

‘They will do anything to get money – steal a person’s wallet, iPhone, jewelry. And then they will attack their victim and kick them half to death.

Swedish police revealed they have sent plain-clothes officers to monitor swimming baths in Stockholm after increased reports of sexual harassment of girls and women.
