That means “head money,” as in bounty.

Bounty offered over Berlin power grid attack – German authorities have offered a €1 million bounty for tips related to this month’s massive Berlin blackout.

German authorities have issued a €1 million ($1.1 million) reward for information leading to the arrest of those responsible for an attack on electricity infrastructure in Berlin.

The arson attack on January 3 targeted high-voltage cables. It left some 45,000 households in south-western Berlin without electricity and heating during sub-zero temperatures earlier this month. It took more than four days to reconnect all residents back to the grid, making it the longest power outage in the city since the Second World War.
