Crime and safety

Bangkok has a relatively moderate crime rate when compared to urban counterparts around the world. Traffic accidents are a major hazard, while natural disasters are rare. Intermittent episodes of political unrest have resulted in losses of life.

Although the crime threat in Bangkok is relatively low, non-confrontational crimes of opportunity such as pick-pocketing, purse-snatching, and credit card fraud occur with frequency. Bangkok's growth since the 1960s has been followed by increasing crime rates partly driven by urbanization, migration, unemployment and poverty. By the late 1980s, Bangkok's crime rates were about four times that of the rest of the country. The police have long been preoccupied with street crimes ranging from housebreaking to assault and murder. The 1990s saw the emergence of vehicle theft and organized crime, particularly by foreign gangs. Drug trafficking, especially that of ya ba methamphetamine pills, is also chronic.

According to police statistics, the most common complaint received by the Metropolitan Police Bureau in 2010 was housebreaking, with 12,347 cases. This was followed by 5,504 cases of motorcycle thefts, 3,694 cases of assault, and 2,836 cases of embezzlement. Serious offences included 183 murders, 81 gang robberies, 265 robberies, 1 kidnapping and 9 arson cases. Offences against the state were by far more common, and included 54,068 drug-related cases, 17,239 cases involving prostitution and 8,634 related to gambling. The Thailand Crime Victim Survey conducted by the Office of Justice Affairs of the Ministry of Justice found that 2.7 percent of surveyed households reported a member being victim of a crime in 2007. Of these, 96.1 percent were crimes against property, 2.6 percent were crimes against life and body, and 1.4 percent were information-related crimes.

Political demonstrations and protests are common in Bangkok. While most events since 1992 had been peaceful, the series of protests alternately staged by the Yellow Shirts and Red Shirts since 2006 have often turned violent. Red Shirt demonstrations during March–May 2010 ended in a crackdown in which 92 were killed, including armed and unarmed protesters, security forces, civilians and journalists. Terrorist incidents have also occurred in Bangkok, most notably a series of bombings on the 2006–07 New Year's Eve.

Traffic accidents are a major hazard in Bangkok. There were 37,985 accidents in the city in 2010, resulting in 16,602 injuries and 456 deaths as well as 426.42 million baht in damages. However, the rate of fatal accidents is much lower than in the rest of Thailand. While accidents in Bangkok amounted to 50.9 percent of the entire country, only 6.2 percent of fatalities occurred in the city. Another serious public health hazard comes from Bangkok's stray dogs. Up to 300,000 strays are estimated to roam the city's streets, and dog bites are among the most common injuries treated in the emergency departments of the city's hospitals. Rabies is prevalent among the dog population, and treatment for bites pose a heavy public burden. Natural disasters, on the other hand, are rare. While the severe floods of 2011 adversely affected Bangkok, no deaths were reported in city itself. Such extreme flooding is uncommon, although limited flooding does occur regularly in some neighbourhoods.
