Talk about bad blood between neighbours.

On Nov. 2, a 71-year-old lorry attendant, Sim Ann Heng, was sentenced to two weeks' jail on two charges of harassment.

On July 11, Sim smeared his own faeces on the letterbox of a 67-year-old resident, Tan Yam Chwee.

Four days later, he pasted a mock obituary photo above the Tan's letterbox.

The incidents took place at an HDB estate in Commonwealth Avenue.

According to Yahoo! News, Sim's actions were due to previous staring incidents with Tan and the suspicion that Tan was gossiping about him to their neighbours.

Both Sim and Tan live two floors apart, with Sim living on the 12th floor and Tan living on the 14th floor.

How both incidents unfolded

The Straits Times reported that Sim had smeared his own faeces on Tan's letterbox between 6.30am and 7.50am.

When Tan discovered the mess, he called the police. Town council workers had to clean up the mess.

A CCTV camera was then installed on the ground floor.

Subsequently, on July 15, a policeman who was on patrol spotted a man writing something on the letterbox.

Yahoo! News reports that this turned out to be a mock obituary photo for Tan.

Sim had cut out an actual obituary photo, wrote Tan's name at the top, misspelled as "Yam Chee", then pasted it above Tan's letterbox.

Sim also pasted a newspaper cut-out of the word "Obituaries" on the opening flag of Tan's letterbox.

Already serving an earlier sentence for assaulting Tan

Sim is currently serving a five-month jail sentence for assaulting Tan on June 19.

He will begin serving his two-week sentence for harassment once he finishes his first sentence.

Sim had initially appealed his five-month jail sentence.

After the incidents of July 11 and 15, Sim withdrew his appeal on Aug. 13, and began serving his sentence for assault on the same day.
