A stalker obsessed with a young Spanish actress shot at her with a crossbow before being wrestled to the ground and arrested outside a Madrid theater, police said Monday.

The official says the arrow from the crossbow aimed at Sara Casasnovas hit a male bystander, who was not seriously hurt in the attack Sunday evening.

The suspected attacker is a 39-year-old German, who became obsessed with Casasnovas after seeing her a year and a half ago on Spanish National Television's international channel.

The official told The Associated Press the man had been sending the 25-year-old actress love letters and attacked her outside a theater where she had just finished a performance of "Night of the Iguana," after she told him she wanted nothing to do with him.

The man was carrying a military-style backpack that contained a second crossbow, arrows with harpoon-style tips, a can of gasoline, handcuffs, rope, a canister of mace and a poster from a play in which Casasnovas had performed a few months ago, the official said.

The official spoke on condition of anonymity in line with department rules.
