When she was arrested: RAF terrorist Klette is said to have used a simple trick to warn fleeing accomplices. Her two suspected accomplices are still on the run - she may have been able to warn one of them.

She wrote a message and then flushed her cell phone's SIM card down the toilet, they said. According to research, Burkhard Spiegel's cell phone was no longer in use since the day of Klette's arrest. The 55-year-old lived in a trailer in Berlin-Friedrichshain under the code name “Martin”.
