Lincoln Police say Tuesday night around 10 p.m. a man walking to a grocery store was mugged and beaten up. Police say the victim, 44-year-old Mark Yoacum was punched and kicked several times in the head and suffered several cuts and bruises.

Yoacum says the suspects got away with about fifteen dollars, but most importantly stole a special notebook. Yoacum who is bi-polar says the notebook contained personal writings about himself living with the disease. Yoacum says he was in the middle of writing a book called, I Never Clapped. Yoacum says, "Remember the song that goes, if your happy and you know it clap your hands. Well, I never clapped."

The suspects in the case have been described as two white males. One suspect is about six feet tall and the other about five feet five inches.

Yoacum says his injuries sting, but his missing notebook hurts even more.
