A man in Shishi, Fujian Province who attacked a neighbor for sleeping with his wife told police his suspicions piqued when he unlocked his neighbor's cellphone by entering his wife's birthday, media reported Wednesday. 

The 25-year-old man surnamed Zhang committed the assault Tuesday after catching the pair in a rented flat. 

Hongshan township police responded after receiving a call from Zhang's distressed wife.

Zhang said he became suspicious in mid-October during a basketball game with his neighbor, surnamed Wang.

Zhang said he picked up Wang's phone and, mistaking it for his own, entered his wife's birthday, which unlocked it. 

Wang has agreed not to press charges following police mediation, read the report.
