The father of Sgt. Bowe Bergdahl creepily harassed a pair of twin sisters in Hailey, Idaho, for several months, according to police reports obtained by the Daily Mail.

In 2011, long before Robert “Bob” Bergdahl began learning Pashto and Arabic or tweeted a Taliban spokesman, the bizarro bearded dad stalked Lacey and Allie Hillman, police documents say. He allegedly tried to steal a peek at one of the twins in the shower and even stole a little gnome from their garden.

For anyone who has a daughter – or is a daughter – the allegations are frightening.

The Hillman sisters told police that Bergdahl, a UPS deliveryman, harassed them for over four months. Bergdahl’s son was about two years into his Taliban captivity during this period. The elder Bergdahl was – and remains – married to Jani Bergdahl, the mother of Bowe Bergdahl.

The twins said Bergdahl, 51, drove by their residence – apparently they lived together – several times each day.

On one occasion, the sisters claimed, he left an angry note charging that one of the then-twentysomething sisters was “two-timing” him.

Later, he allegedly left a note saying, “I am sorry for whatever I did.”

A few weeks later, the sisters told police, Bergdahl confronted Allie Hillman at her front door after her boyfriend had left her house. She told police Bergdahl knocked on the door and said, while laughing, “What are you two-timing me, bitch?” according to the Mail.

Another time, Bergdahl allegedly sneaked around the outside of the home for a few hours and approached the house as Lacey Hillman was taking a shower.

Lacey told local cops that she heard a noise and stepped out of the shower wearing just a towel. She walked to a glass door. There, she told police, she saw a “shadowed person.” It was Bergdahl, she said. He tried to get her to come closer to the door.

“According to Lacey, a minute passed while Robert shook his head on the other side of the closed door and he eventually left while throwing his hands up in the air,” the 2011 police report states.

It was after this voyeuristic episode that the sisters went to the police, saying they were “very scared,” reports the Mail.

The twins noted to police that they understood Bergdahl was likely suffering emotional stress since his son had been a prisoner of war for two years, but they said they wanted the stalking to stop.

The cops had a chat with Bergdahl, warning him to stay away from the twins’ residence and places of work. He agreed to these terms. The Hillman twins agreed not to press charges.

Bowe Bergdahl, a soldier in the U.S. army, was held captive by the Taliban-aligned Haqqani network in Afghanistan from June 2009 until his release in May 2014. The release was part of a five-for-one prisoner trade with the Taliban that the Obama administration secretly orchestrated. (RELATED: The Taliban Wanted A 6th Guy Back, But He Died On An Elliptical)

The Bergdahl clan is expected to be reunited this weekend in San Antonio.
