July 28, 1961 - One thousand thirty refugees made their way to West Berlin in the 24 hours ending at 4 p.m. today, indicating that East German efforts to halt the flow have been largely ineffective. Since last week, tight controls of Berlin-bound trains and highways leading to the city have been in force. Travelers unable to give a satisfactory explanation of their trips are being sent back. So far this month nearly 26,000 East Germans have successfully committed the crime of "flight from the German People's Republic." Those caught are liable to two years' imprisonment.
