PRAGUE, Dec. 10 (Xinhua) -- The number of illegally staying migrants uncovered by Czech police rose by almost 80 percent in 2015, local media reported on Saturday, quoting an annual report compiled by Czech Interior Minister Milan Chovanec.

According to the report, the foreigners illegally staying in the Czech Republic were mostly from Syria, Ukraine and Kuwait.

In 2015, 8,563 persons were found as illegal migrants. Compared with 2014, there was a growth by 3,741 persons, or 77.6 percent.

Among them, 240 persons were found when trying to illegally across the Schengen border and 8,323 during their illegal stay in the country.

The report said that 582 people were repeatedly found illegally staying in the Czech Republic. They were mostly from Ukraine, Kuwait and Saudi Arabia. Some of them were detained while they carried several travelling documents.

In 2015, Czech police conducted more than 250,000 checks on illegal stay.

Although the developments in the past years have shown that for many, the Czech Republic has become the country of their destination, it is still widely used by illegal migrants to other European countries, said the report.
