A handmade bomb exploded on Friday inside the house of a former prosecutor who has been honored as an active anti-corruption whistleblower in central Vietnam, but there was no casualty, police said.
The bomb exploded at around 11 p.m. on September 16 on the first floor of the house of Nguyen Van Thanh, 69, in Tan Ky District, Nghe An Province.
At that time Thanh and his wife were sleeping on the second floor, according to the local police.
Local police are trying to establish who threw the bomb into Thanh's house.
Thanh was a retired officer of the Tan Ky District People's Procuracy. He has been known for actively exposing corruption acts of local officials and helping local people to regain illegally appropriated land over the last years.
Following Thanh's petitions, a number of local officials had been disciplined and billions of dongs and hundreds of square meters of land reclaimed.
In January, Thanh was among 18 outstanding whistleblowers honored by Nghe An provincial authorities.
The Nguoi Lao Dong newspaper reported that Thanh had since received anonymous letters and phone calls in which strangers threatened him and asked him to stop whistleblowing acts.
Someone had also thrown stones to break the windows of his house.
After local newspapers ran stories about the threats he received, in February Prime Minister Nguyen Tan Dung asked Nghe An Province authorities to take measures to protect Thanh and his family.
