Almost one in every eight migrants arriving in Germany disappears after his or her registration, the Sueddeutsche Zeitung daily reported Friday, citing information from the Interior Ministry.
Around 13 per cent of the 1.1 million migrants and refugees registered in the country last year did not show up at the reception centres to which they were sent, the ministry said in response to a parliamentary question from the Left Party (Die Linke), according to the report.
This amounts to over 130,000 people unaccounted for. Many could have travelled onwards to other countries or become involved in illegal work or crime, the Interior Ministry said in its response.
The report comes one day after the head of the Ministry for Migration and Refugees (BAMF), Frank-Juergen Weise, said that authorities do not know the names and identities of up to 400,000 people in Germany.
According to the report, the ministry said it is becoming increasingly difficult due to a lack of information to implement the so-called Dublin rule, which stipulates that asylum seekers' applications must be processed in the EU country in which they first set foot.
German authorities asked another EU member to take back an applicant in one in 10 cases in 2015. In 2014, a request was sent in one in five cases.
Germany suspended the Dublin regulation for refugees fleeing the Syrian civil war for a short period last year.
