In Madera, California, police and FBI are investigating a firebomb attack against a Planned Parenthood office that has been open for 20 years without incident: Molotov Cocktail thrown at Madera’s Planned Parenthood.

This attack comes one week after a brick was thrown through the window of a local mosque and anti-Muslim signs posted on its walls, by a group using the name “American Nationalist Brotherhood.” One of the signs: “No Temple for the god of terrorism at Ground Zero.”

FRESNO, Calif. (KFSN) — Madera’s Planned Parenthood clinic is closed Thursday after someone firebombed it with a Molotov cocktail. The FBI is investigating this case as it continues to search for clues in an attack on a mosque last week on the other side of town.

This Planned Parenthood clinic in Madera has been open for 20 years and officials here say they’ve never seen any kind of violent crime before. Madera Police are investigating the crime but they’re also getting help from the FBI who happen to be investigating another crime in Madera at the same time.

Burnt blinds on the grass and a boarded up window show the damage caused by a firebombing attack early Thursday morning.

“Upon arrival responding officers discovered that Planned Parenthood had been attacked by an unknown person with an incendiary device.” said Madera Police Chief Michael Kime.

Madera Police do not have anyone in custody but a spokesperson with Planned Parenthood says she has a good idea of who it might be. “I believe it’s extremists who are, want to make a statement.” said public affairs director Patsy Montgomery.
