Police forces involved in anti-Maoist operations have been asked to preserve handwritten posters circulated by the rebels in their areas to get more information about those who are involved in those activities.
The police personnel have been asked to look minutely at the type of handwriting used in the posters and maintain a databank which can help them connect different cases and accused. The posters, according to officials, will be able to ascertain whether it was created by a “literate person” or an “amateur”, narrowing down the scope of search.
Even the kind of paint brushes recovered from the spot could give an insight on whether a local or an outsider was involved.
“If a paint brush has been made of local vegetation or reed it means some local has been involved. If the brush is of finer quality then it suggests that it was brought from outside,” said a senior official.
The Central Reserve Police Force (CRPF) has prepared a presentation on preserving the forensic evidence that will be given to all the police forces of the nine states that are facing Maoist insurgency.
“The handwriting specimen should be matched with the records available in the schools, ration shops, mobile phone dealers among others to narrow down on the suspects,” said a senior official.
The internal presentation prepared by the CRPF, which leads operations in all the Maoist-affected states, also describes the kind of DNA samples that can be lifted from training camps and Maoist hideouts after they have been raided.
“Small things like cigarette butts, used condoms, matchsticks, clothes, utensils, all these should be collected carefully to preserve DNA evidence. These items should not be disposed of and stored for future DNA analysis that will lead to better conviction rate,” said an official.
Officers involved in anti-Maoist operations said there is trouble identifying the Maoists from the ordinary villagers and the evidences will help.
“There are occasions when a spot where an operation has been carried out was not forensically preserved leading to loss of vital information,” said the official.
