On the way to Prague's Dejvice, their chase was ended, and the StB members caught up with them and they were then, detained by state security. The three were released later in the evening, apparently in response to the news which travelled abroad. The published Declaration of Charter 77 had given rise to a number of restrictive measures by the Czechoslovak regime. Its signatories were subjected to a constant persecution of the regime through police surveillance, house searches, job cuts, seizure of passports, detention, physical violence, imprisonment or expulsion from the country.
